But much of the code needed to handle controls +is actually not driver specific and can be moved to the V4L core framework. + +After all, the only part that a driver developer is interested in is: + +1) How do I add a control? +2) How do I set the control's value? (i.e. s_ctrl) + +And occasionally: + +3) How do I get the control's value? (i.e. g_volatile_ctrl) +4) How do I validate the user's proposed control value? (i.e. try_ctrl) + +All the rest is something that can be done centrally. + +The control framework was created in order to implement all the rules of the +V4L2 specification with respect to controls in a central place. And to make +life as easy as possible for the driver developer. + +Note that the control framework relies on the presence of a struct v4l2_device +for V4L2 drivers and struct v4l2_subdev for sub-device drivers. + + +Objects in the framework +======================== + +There are two main objects: + +The v4l2_ctrl object describes the control properties and keeps track of the +control's value (both the current value and the proposed new value). + +v4l2_ctrl_handler is the object that keeps track of controls. It maintains a +list of v4l2_ctrl objects that it owns and another list of references to +controls, possibly to controls owned by other handlers. + + +Basic usage for V4L2 and sub-device drivers +=========================================== + +1) Prepare the driver: + +1.1) Add the handler to your driver's top-level struct: + + struct foo_dev { + ... + struct v4l2_ctrl_handler ctrl_handler; + ... + }; + + struct foo_dev *foo; + +1.2) Initialize the handler: + + v4l2_ctrl_handler_init(&foo->ctrl_handler, nr_of_controls); + + The second argument is a hint telling the function how many controls this + handler is expected to handle. It will allocate a hashtable based on this + information. It is a hint only. + +1.3) Hook the control handler into the driver: + +1.3.1) For V4L2 drivers do this: + + struct foo_dev { + ... + struct v4l2_device v4l2_dev; + ... + struct v4l2_ctrl_handler ctrl_handler; + ... + }; + + foo->v4l2_dev.ctrl_handler = &foo->ctrl_handler; + + Where foo->v4l2_dev is of type struct v4l2_device. + + Finally, remove all control functions from your v4l2_ioctl_ops: + vidioc_queryctrl, vidioc_querymenu, vidioc_g_ctrl, vidioc_s_ctrl, + vidioc_g_ext_ctrls, vidioc_try_ext_ctrls and vidioc_s_ext_ctrls. + Those are now no longer needed. + +1.3.2) For sub-device drivers do this: + + struct foo_dev { + ... + struct v4l2_subdev sd; + ... + struct v4l2_ctrl_handler ctrl_handler; + ... + }; + + foo->sd.ctrl_handler = &foo->ctrl_handler; + + Where foo->sd is of type struct v4l2_subdev. + + And set all core control ops in your struct v4l2_subdev_core_ops to these + helpers: + + .queryctrl = v4l2_subdev_queryctrl, + .querymenu = v4l2_subdev_querymenu, + .g_ctrl = v4l2_subdev_g_ctrl, + .s_ctrl = v4l2_subdev_s_ctrl, + .g_ext_ctrls = v4l2_subdev_g_ext_ctrls, + .try_ext_ctrls = v4l2_subdev_try_ext_ctrls, + .s_ext_ctrls = v4l2_subdev_s_ext_ctrls, + + Note: this is a temporary solution only. Once all V4L2 drivers that depend + on subdev drivers are converted to the control framework these helpers will + no longer be needed. + +1.4) Clean up the handler at the end: + + v4l2_ctrl_handler_free(&foo->ctrl_handler); + + +2) Add controls: + +You add non-menu controls by calling v4l2_ctrl_new_std: + + struct v4l2_ctrl *v4l2_ctrl_new_std(struct v4l2_ctrl_handler *hdl, + const struct v4l2_ctrl_ops *ops, + u32 id, s32 min, s32 max, u32 step, s32 def); + +Menu controls are added by calling v4l2_ctrl_new_std_menu: + + struct v4l2_ctrl *v4l2_ctrl_new_std_menu(struct v4l2_ctrl_handler *hdl, + const struct v4l2_ctrl_ops *ops, + u32 id, s32 max, s32 skip_mask, s32 def); + +These functions are typically called right after the v4l2_ctrl_handler_init: + + v4l2_ctrl_handler_init(&foo->ctrl_handler, nr_of_controls); + v4l2_ctrl_new_std(&foo->ctrl_handler, &foo_ctrl_ops, + V4L2_CID_BRIGHTNESS, 0, 255, 1, 128); + v4l2_ctrl_new_std(&foo->ctrl_handler, &foo_ctrl_ops, + V4L2_CID_CONTRAST, 0, 255, 1, 128); + v4l2_ctrl_new_std_menu(&foo->ctrl_handler, &foo_ctrl_ops, + V4L2_CID_POWER_LINE_FREQUENCY, + V4L2_CID_POWER_LINE_FREQUENCY_60HZ, 0, + V4L2_CID_POWER_LINE_FREQUENCY_DISABLED); + ... + if (foo->ctrl_handler.error) { + int err = foo->ctrl_handler.error; + + v4l2_ctrl_handler_free(&foo->ctrl_handler); + return err; + } + +The v4l2_ctrl_new_std function returns the v4l2_ctrl pointer to the new +control, but if you do not need to access the pointer outside the control ops, +then there is no need to store it. + +The v4l2_ctrl_new_std function will fill in most fields based on the control +ID except for the min, max, step and default values. These are passed in the +last four arguments. These values are driver specific while control attributes +like type, name, flags are all global. The control's current value will be set +to the default value. + +The v4l2_ctrl_new_std_menu function is very similar but it is used for menu +controls. There is no min argument since that is always 0 for menu controls, +and instead of a step there is a skip_mask argument: if bit X is 1, then menu +item X is skipped. + +Note that if something fails, the function will return NULL or an error and +set ctrl_handler->error to the error code. If ctrl_handler->error was already +set, then it will just return and do nothing. This is also true for +v4l2_ctrl_handler_init if it cannot allocate the internal data structure. + +This makes it easy to init the handler and just add all controls and only check +the error code at the end. Saves a lot of repetitive error checking. + +It is recommended to add controls in ascending control ID order: it will be +a bit faster that way. + +3) Optionally force initial control setup: + + v4l2_ctrl_handler_setup(&foo->ctrl_handler); + +This will call s_ctrl for all controls unconditionally. Effectively this +initializes the hardware to the default control values. It is recommended +that you do this as this ensures that both the internal data structures and +the hardware are in sync. + +4) Finally: implement the v4l2_ctrl_ops + + static const struct v4l2_ctrl_ops foo_ctrl_ops = { + .s_ctrl = foo_s_ctrl, + }; + +Usually all you need is s_ctrl: + + static int foo_s_ctrl(struct v4l2_ctrl *ctrl) + { + struct foo *state = container_of(ctrl->handler, struct foo, ctrl_handler); + + switch (ctrl->id) { + case V4L2_CID_BRIGHTNESS: + write_reg(0x123, ctrl->val); + break; + case V4L2_CID_CONTRAST: + write_reg(0x456, ctrl->val); + break; + } + return 0; + } + +The control ops are called with the v4l2_ctrl pointer as argument. +The new control value has already been validated, so all you need to do is +to actually update the hardware registers. + +You're done! And this is sufficient for most of the drivers we have. No need +to do any validation of control values, or implement QUERYCTRL/QUERYMENU. And +G/S_CTRL as well as G/TRY/S_EXT_CTRLS are automatically supported. + + +============================================================================== + +The remainder of this document deals with more advanced topics and scenarios. +In practice the basic usage as described above is sufficient for most drivers. + +=============================================================================== + + +Inheriting Controls +=================== + +When a sub-device is registered with a V4L2 driver by calling +v4l2_device_register_subdev() and the ctrl_handler fields of both v4l2_subdev +and v4l2_device are set, then the controls of the subdev will become +automatically available in the V4L2 driver as well. If the subdev driver +contains controls that already exist in the V4L2 driver, then those will be +skipped (so a V4L2 driver can always override a subdev control). + +What happens here is that v4l2_device_register_subdev() calls +v4l2_ctrl_add_handler() adding the controls of the subdev to the controls +of v4l2_device. + + +Accessing Control Values +======================== + +The v4l2_ctrl struct contains these two unions: + + /* The current control value. */ + union { + s32 val; + s64 val64; + char *string; + } cur; + + /* The new control value. */ + union { + s32 val; + s64 val64; + char *string; + }; + +Within the control ops you can freely use these. The val and val64 speak for +themselves. The string pointers point to character buffers of length +ctrl->maximum + 1, and are always 0-terminated. + +In most cases 'cur' contains the current cached control value. When you create +a new control this value is made identical to the default value. After calling +v4l2_ctrl_handler_setup() this value is passed to the hardware. It is generally +a good idea to call this function. + +Whenever a new value is set that new value is automatically cached. This means +that most drivers do not need to implement the g_volatile_ctrl() op. The +exception is for controls that return a volatile register such as a signal +strength read-out that changes continuously. In that case you will need to +implement g_volatile_ctrl like this: + + static int foo_g_volatile_ctrl(struct v4l2_ctrl *ctrl) + { + switch (ctrl->id) { + case V4L2_CID_BRIGHTNESS: + ctrl->cur.val = read_reg(0x123); + break; + } + } + +The 'new value' union is not used in g_volatile_ctrl. In general controls +that need to implement g_volatile_ctrl are read-only controls. + +To mark a control as volatile you have to set the is_volatile flag: + + ctrl = v4l2_ctrl_new_std(&sd->ctrl_handler, ...); + if (ctrl) + ctrl->is_volatile = 1; + +For try/s_ctrl the new values (i.e. as passed by the user) are filled in and +you can modify them in try_ctrl or set them in s_ctrl. The 'cur' union +contains the current value, which you can use (but not change!) as well. + +If s_ctrl returns 0 (OK), then the control framework will copy the new final +values to the 'cur' union. + +While in g_volatile/s/try_ctrl you can access the value of all controls owned +by the same handler since the handler's lock is held. If you need to access +the value of controls owned by other handlers, then you have to be very careful +not to introduce deadlocks. + +Outside of the control ops you have to go through to helper functions to get +or set a single control value safely in your driver: + + s32 v4l2_ctrl_g_ctrl(struct v4l2_ctrl *ctrl); + int v4l2_ctrl_s_ctrl(struct v4l2_ctrl *ctrl, s32 val); + +These functions go through the control framework just as VIDIOC_G/S_CTRL ioctls +do. Don't use these inside the control ops g_volatile/s/try_ctrl, though, that +will result in a deadlock since these helpers lock the handler as well. + +You can also take the handler lock yourself: + + mutex_lock(&state->ctrl_handler.lock); + printk(KERN_INFO "String value is '%s'\n", ctrl1->cur.string); + printk(KERN_INFO "Integer value is '%s'\n", ctrl2->cur.val); + mutex_unlock(&state->ctrl_handler.lock); + + +Menu Controls +============= + +The v4l2_ctrl struct contains this union: + + union { + u32 step; + u32 menu_skip_mask; + }; + +For menu controls menu_skip_mask is used. What it does is that it allows you +to easily exclude certain menu items. This is used in the VIDIOC_QUERYMENU +implementation where you can return -EINVAL if a certain menu item is not +present. Note that VIDIOC_QUERYCTRL always returns a step value of 1 for +menu controls. + +A good example is the MPEG Audio Layer II Bitrate menu control where the +menu is a list of standardized possible bitrates. But in practice hardware +implementations will only support a subset of those. By setting the skip +mask you can tell the framework which menu items should be skipped. Setting +it to 0 means that all menu items are supported. + +You set this mask either through the v4l2_ctrl_config struct for a custom +control, or by calling v4l2_ctrl_new_std_menu(). + + +Custom Controls +=============== + +Driver specific controls can be created using v4l2_ctrl_new_custom(): + + static const struct v4l2_ctrl_config ctrl_filter = { + .ops = &ctrl_custom_ops, + .id = V4L2_CID_MPEG_CX2341X_VIDEO_SPATIAL_FILTER, + .name = "Spatial Filter", + .type = V4L2_CTRL_TYPE_INTEGER, + .flags = V4L2_CTRL_FLAG_SLIDER, + .max = 15, + .step = 1, + }; + + ctrl = v4l2_ctrl_new_custom(&foo->ctrl_handler, &ctrl_filter, NULL); + +The last argument is the priv pointer which can be set to driver-specific +private data. + +The v4l2_ctrl_config struct also has fields to set the is_private and is_volatile +flags. + +If the name field is not set, then the framework will assume this is a standard +control and will fill in the name, type and flags fields accordingly. + + +Active and Grabbed Controls +=========================== + +If you get more complex relationships between controls, then you may have to +activate and deactivate controls. For example, if the Chroma AGC control is +on, then the Chroma Gain control is inactive. That is, you may set it, but +the value will not be used by the hardware as long as the automatic gain +control is on. Typically user interfaces can disable such input fields. + +You can set the 'active' status using v4l2_ctrl_activate(). By default all +controls are active. Note that the framework does not check for this flag. +It is meant purely for GUIs. The function is typically called from within +s_ctrl. + +The other flag is the 'grabbed' flag. A grabbed control means that you cannot +change it because it is in use by some resource. Typical examples are MPEG +bitrate controls that cannot be changed while capturing is in progress. + +If a control is set to 'grabbed' using v4l2_ctrl_grab(), then the framework +will return -EBUSY if an attempt is made to set this control. The +v4l2_ctrl_grab() function is typically called from the driver when it +starts or stops streaming. + + +Control Clusters +================ + +By default all controls are independent from the others. But in more +complex scenarios you can get dependencies from one control to another. +In that case you need to 'cluster' them: + + struct foo { + struct v4l2_ctrl_handler ctrl_handler; +#define AUDIO_CL_VOLUME (0) +#define AUDIO_CL_MUTE (1) + struct v4l2_ctrl *audio_cluster[2]; + ... + }; + + state->audio_cluster[AUDIO_CL_VOLUME] = + v4l2_ctrl_new_std(&state->ctrl_handler, ...); + state->audio_cluster[AUDIO_CL_MUTE] = + v4l2_ctrl_new_std(&state->ctrl_handler, ...); + v4l2_ctrl_cluster(ARRAY_SIZE(state->audio_cluster), state->audio_cluster); + +From now on whenever one or more of the controls belonging to the same +cluster is set (or 'gotten', or 'tried'), only the control ops of the first +control ('volume' in this example) is called. You effectively create a new +composite control. Similar to how a 'struct' works in C. + +So when s_ctrl is called with V4L2_CID_AUDIO_VOLUME as argument, you should set +all two controls belonging to the audio_cluster: + + static int foo_s_ctrl(struct v4l2_ctrl *ctrl) + { + struct foo *state = container_of(ctrl->handler, struct foo, ctrl_handler); + + switch (ctrl->id) { + case V4L2_CID_AUDIO_VOLUME: { + struct v4l2_ctrl *mute = ctrl->cluster[AUDIO_CL_MUTE]; + + write_reg(0x123, mute->val ? 0 : ctrl->val); + break; + } + case V4L2_CID_CONTRAST: + write_reg(0x456, ctrl->val); + break; + } + return 0; + } + +In the example above the following are equivalent for the VOLUME case: + + ctrl == ctrl->cluster[AUDIO_CL_VOLUME] == state->audio_cluster[AUDIO_CL_VOLUME] + ctrl->cluster[AUDIO_CL_MUTE] == state->audio_cluster[AUDIO_CL_MUTE] + +Note that controls in a cluster may be NULL. For example, if for some +reason mute was never added (because the hardware doesn't support that +particular feature), then mute will be NULL. So in that case we have a +cluster of 2 controls, of which only 1 is actually instantiated. The +only restriction is that the first control of the cluster must always be +present, since that is the 'master' control of the cluster. The master +control is the one that identifies the cluster and that provides the +pointer to the v4l2_ctrl_ops struct that is used for that cluster. + +Obviously, all controls in the cluster array must be initialized to either +a valid control or to NULL. + + +VIDIOC_LOG_STATUS Support +========================= + +This ioctl allow you to dump the current status of a driver to the kernel log. +The v4l2_ctrl_handler_log_status(ctrl_handler, prefix) can be used to dump the +value of the controls owned by the given handler to the log. You can supply a +prefix as well. If the prefix didn't end with a space, then ': ' will be added +for you. + + +Different Handlers for Different Video Nodes +============================================ + +Usually the V4L2 driver has just one control handler that is global for +all video nodes. But you can also specify different control handlers for +different video nodes. You can do that by manually setting the ctrl_handler +field of struct video_device. + +That is no problem if there are no subdevs involved but if there are, then +you need to block the automatic merging of subdev controls to the global +control handler. You do that by simply setting the ctrl_handler field in +struct v4l2_device to NULL. Now v4l2_device_register_subdev() will no longer +merge subdev controls. + +After each subdev was added, you will then have to call v4l2_ctrl_add_handler +manually to add the subdev's control handler (sd->ctrl_handler) to the desired +control handler. This control handler may be specific to the video_device or +for a subset of video_device's. For example: the radio device nodes only have +audio controls, while the video and vbi device nodes share the same control +handler for the audio and video controls. + +If you want to have one handler (e.g. for a radio device node) have a subset +of another handler (e.g. for a video device node), then you should first add +the controls to the first handler, add the other controls to the second +handler and finally add the first handler to the second. For example: + + v4l2_ctrl_new_std(&radio_ctrl_handler, &radio_ops, V4L2_CID_AUDIO_VOLUME, ...); + v4l2_ctrl_new_std(&radio_ctrl_handler, &radio_ops, V4L2_CID_AUDIO_MUTE, ...); + v4l2_ctrl_new_std(&video_ctrl_handler, &video_ops, V4L2_CID_BRIGHTNESS, ...); + v4l2_ctrl_new_std(&video_ctrl_handler, &video_ops, V4L2_CID_CONTRAST, ...); + v4l2_ctrl_add_handler(&video_ctrl_handler, &radio_ctrl_handler); + +Or you can add specific controls to a handler: + + volume = v4l2_ctrl_new_std(&video_ctrl_handler, &ops, V4L2_CID_AUDIO_VOLUME, ...); + v4l2_ctrl_new_std(&video_ctrl_handler, &ops, V4L2_CID_BRIGHTNESS, ...); + v4l2_ctrl_new_std(&video_ctrl_handler, &ops, V4L2_CID_CONTRAST, ...); + v4l2_ctrl_add_ctrl(&radio_ctrl_handler, volume); + +What you should not do is make two identical controls for two handlers. +For example: + + v4l2_ctrl_new_std(&radio_ctrl_handler, &radio_ops, V4L2_CID_AUDIO_MUTE, ...); + v4l2_ctrl_new_std(&video_ctrl_handler, &video_ops, V4L2_CID_AUDIO_MUTE, ...); + +This would be bad since muting the radio would not change the video mute +control. The rule is to have one control for each hardware 'knob' that you +can twiddle. + + +Finding Controls +================ + +Normally you have created the controls yourself and you can store the struct +v4l2_ctrl pointer into your own struct. + +But sometimes you need to find a control from another handler that you do +not own. For example, if you have to find a volume control from a subdev. + +You can do that by calling v4l2_ctrl_find: + + struct v4l2_ctrl *volume; + + volume = v4l2_ctrl_find(sd->ctrl_handler, V4L2_CID_AUDIO_VOLUME); + +Since v4l2_ctrl_find will lock the handler you have to be careful where you +use it. For example, this is not a good idea: + + struct v4l2_ctrl_handler ctrl_handler; + + v4l2_ctrl_new_std(&ctrl_handler, &video_ops, V4L2_CID_BRIGHTNESS, ...); + v4l2_ctrl_new_std(&ctrl_handler, &video_ops, V4L2_CID_CONTRAST, ...); + +...and in video_ops.s_ctrl: + + case V4L2_CID_BRIGHTNESS: + contrast = v4l2_find_ctrl(&ctrl_handler, V4L2_CID_CONTRAST); + ... + +When s_ctrl is called by the framework the ctrl_handler.lock is already taken, so +attempting to find another control from the same handler will deadlock. + +It is recommended not to use this function from inside the control ops. + + +Inheriting Controls +=================== + +When one control handler is added to another using v4l2_ctrl_add_handler, then +by default all controls from one are merged to the other. But a subdev might +have low-level controls that make sense for some advanced embedded system, but +not when it is used in consumer-level hardware. In that case you want to keep +those low-level controls local to the subdev. You can do this by simply +setting the 'is_private' flag of the control to 1: + + static const struct v4l2_ctrl_config ctrl_private = { + .ops = &ctrl_custom_ops, + .id = V4L2_CID_..., + .name = "Some Private Control", + .type = V4L2_CTRL_TYPE_INTEGER, + .max = 15, + .step = 1, + .is_private = 1, + }; + + ctrl = v4l2_ctrl_new_custom(&foo->ctrl_handler, &ctrl_private, NULL); + +These controls will now be skipped when v4l2_ctrl_add_handler is called. + + +V4L2_CTRL_TYPE_CTRL_CLASS Controls +================================== + +Controls of this type can be used by GUIs to get the name of the control class. +A fully featured GUI can make a dialog with multiple tabs with each tab +containing the controls belonging to a particular control class. The name of +each tab can be found by querying a special control with ID . + +Drivers do not have to care about this. The framework will automatically add +a control of this type whenever the first control belonging to a new control +class is added. + + +Differences from the Spec +========================= + +There are a few places where the framework acts slightly differently from the +V4L2 Specification. Those differences are described in this section. We will +have to see whether we need to adjust the spec or not. + +1) It is no longer required to have all controls contained in a +v4l2_ext_control array be from the same control class. The framework will be +able to handle any type of control in the array. You need to set ctrl_class +to 0 in order to enable this. If ctrl_class is non-zero, then it will still +check that all controls belong to that control class. + +If you set ctrl_class to 0 and count to 0, then it will only return an error +if there are no controls at all. + +2) Clarified the way error_idx works. For get and set it will be equal to +count if nothing was done yet. If it is less than count then only the controls +up to error_idx-1 were successfully applied. + +3) When attempting to read a button control the framework will return -EACCES +instead of -EINVAL as stated in the spec. It seems to make more sense since +button controls are write-only controls. + +4) Attempting to write to a read-only control will return -EACCES instead of +-EINVAL as the spec says. + +5) The spec does not mention what should happen when you try to set/get a +control class controls. ivtv currently returns -EINVAL (indicating that the +control ID does not exist) while the framework will return -EACCES, which +makes more sense. + + +Proposals for Extensions +======================== + +Some ideas for future extensions to the spec: + +1) Add a V4L2_CTRL_FLAG_HEX to have values shown as hexadecimal instead of +decimal. Useful for e.g. video_mute_yuv. + +2) It is possible to mark in the controls array which controls have been +successfully written and which failed by for example adding a bit to the +control ID. Not sure if it is worth the effort, though. + +3) Trying to set volatile inactive controls should result in -EACCESS. + +4) Add a new flag to mark volatile controls. Any application that wants +to store the state of the controls can then skip volatile inactive controls. +Currently it is not possible to detect such controls. diff --git a/trunk/MAINTAINERS b/trunk/MAINTAINERS index 832f904db114..39d8c5ce9913 100644 --- a/trunk/MAINTAINERS +++ b/trunk/MAINTAINERS @@ -616,10 +616,10 @@ M: Richard Purdie S: Maintained ARM/CORTINA SYSTEMS GEMINI ARM ARCHITECTURE -M: Paulius Zaleckas +M: Hans Ulli Kroll L: linux-arm-kernel@lists.infradead.org (moderated for non-subscribers) -T: git git://gitorious.org/linux-gemini/mainline.git -S: Odd Fixes +T: git git://git.berlios.de/gemini-board +S: Maintained F: arch/arm/mach-gemini/ ARM/EBSA110 MACHINE SUPPORT @@ -641,9 +641,10 @@ T: topgit git://git.openezx.org/openezx.git F: arch/arm/mach-pxa/ezx.c ARM/FARADAY FA526 PORT -M: Paulius Zaleckas +M: Hans Ulli Kroll L: linux-arm-kernel@lists.infradead.org (moderated for non-subscribers) -S: Odd Fixes +S: Maintained +T: git://git.berlios.de/gemini-board F: arch/arm/mm/*-fa* ARM/FOOTBRIDGE ARCHITECTURE @@ -692,6 +693,13 @@ T: git git://git.kernel.org/pub/scm/linux/kernel/git/kristoffer/linux-hpc.git F: arch/arm/mach-sa1100/jornada720.c F: arch/arm/mach-sa1100/include/mach/jornada720.h +ARM/INCOME PXA270 SUPPORT +M: Marek Vasut +L: linux-arm-kernel@lists.infradead.org (moderated for non-subscribers) +S: Maintained +F: arch/arm/mach-pxa/income.c +F: arch/arm/mach-pxa/include/mach-pxa/income.h + ARM/INTEL IOP32X ARM ARCHITECTURE M: Lennert Buytenhek M: Dan Williams @@ -947,8 +955,9 @@ ARM/SHMOBILE ARM ARCHITECTURE M: Paul Mundt M: Magnus Damm L: linux-sh@vger.kernel.org -T: git git://git.kernel.org/pub/scm/linux/kernel/git/lethal/genesis-2.6.git W: http://oss.renesas.com +Q: http://patchwork.kernel.org/project/linux-sh/list/ +T: git git://git.kernel.org/pub/scm/linux/kernel/git/lethal/genesis-2.6.git S: Supported F: arch/arm/mach-shmobile/ F: drivers/sh/ @@ -2203,6 +2212,12 @@ F: drivers/misc/cb710/ F: drivers/mmc/host/cb710-mmc.* F: include/linux/cb710.h +ENE KB2426 (ENE0100/ENE020XX) INFRARED RECEIVER +M: Maxim Levitsky +S: Maintained +F: drivers/media/IR/ene_ir.c +F: drivers/media/IR/ene_ir.h + EPSON 1355 FRAMEBUFFER DRIVER M: Christopher Hoover M: Christopher Hoover diff --git a/trunk/arch/alpha/include/asm/dma-mapping.h b/trunk/arch/alpha/include/asm/dma-mapping.h index 1bce8169733c..4567aca6fdd6 100644 --- a/trunk/arch/alpha/include/asm/dma-mapping.h +++ b/trunk/arch/alpha/include/asm/dma-mapping.h @@ -41,9 +41,7 @@ static inline int dma_set_mask(struct device *dev, u64 mask) #define dma_alloc_noncoherent(d, s, h, f) dma_alloc_coherent(d, s, h, f) #define dma_free_noncoherent(d, s, v, h) dma_free_coherent(d, s, v, h) -#define dma_is_consistent(d, h) (1) #define dma_cache_sync(dev, va, size, dir) ((void)0) -#define dma_get_cache_alignment() L1_CACHE_BYTES #endif /* _ALPHA_DMA_MAPPING_H */ diff --git a/trunk/arch/alpha/include/asm/ioctls.h b/trunk/arch/alpha/include/asm/ioctls.h index 67bb9f6fdbe4..59617c3c2be6 100644 --- a/trunk/arch/alpha/include/asm/ioctls.h +++ b/trunk/arch/alpha/include/asm/ioctls.h @@ -80,6 +80,7 @@ # define TIOCPKT_START 8 # define TIOCPKT_NOSTOP 16 # define TIOCPKT_DOSTOP 32 +# define TIOCPKT_IOCTL 64 #define TIOCNOTTY 0x5422 @@ -91,6 +92,7 @@ #define TIOCGSID 0x5429 /* Return the session ID of FD */ #define TIOCGPTN _IOR('T',0x30, unsigned int) /* Get Pty Number (of pty-mux device) */ #define TIOCSPTLCK _IOW('T',0x31, int) /* Lock/unlock Pty */ +#define TIOCSIG _IOW('T',0x36, int) /* Generate signal on Pty slave */ #define TIOCSERCONFIG 0x5453 #define TIOCSERGWILD 0x5454 @@ -106,7 +108,5 @@ #define TIOCMIWAIT 0x545C /* wait for a change on serial input line(s) */ #define TIOCGICOUNT 0x545D /* read serial port inline interrupt counts */ -#define TIOCGHAYESESP 0x545E /* Get Hayes ESP configuration */ -#define TIOCSHAYESESP 0x545F /* Set Hayes ESP configuration */ #endif /* _ASM_ALPHA_IOCTLS_H */ diff --git a/trunk/arch/alpha/include/asm/scatterlist.h b/trunk/arch/alpha/include/asm/scatterlist.h index 5728c52a7412..017d7471c3c4 100644 --- a/trunk/arch/alpha/include/asm/scatterlist.h +++ b/trunk/arch/alpha/include/asm/scatterlist.h @@ -3,6 +3,4 @@ #include -#define ISA_DMA_THRESHOLD (~0UL) -
