-
-This driver adds support for the multi-touch trackpad on the new Apple
-Macbook Air and Macbook Pro laptops. It replaces the appletouch driver on
-those computers, and integrates well with the synaptics driver of the Xorg
-system.
-
-Known to work on Macbook Air, Macbook Pro Penryn and the new unibody
-Macbook 5 and Macbook Pro 5.
-
-Usage
------
-
-The driver loads automatically for the supported usb device ids, and
-becomes available both as an event device (/dev/input/event*) and as a
-mouse via the mousedev driver (/dev/input/mice).
-
-USB Race
---------
-
-The Apple multi-touch trackpads report both mouse and keyboard events via
-different interfaces of the same usb device. This creates a race condition
-with the HID driver, which, if not told otherwise, will find the standard
-HID mouse and keyboard, and claim the whole device. To remedy, the usb
-product id must be listed in the mouse_ignore list of the hid driver.
-
-Debug output
-------------
-
-To ease the development for new hardware version, verbose packet output can
-be switched on with the debug kernel module parameter. The range [1-9]
-yields different levels of verbosity. Example (as root):
-
-echo -n 9 > /sys/module/bcm5974/parameters/debug
-
-tail -f /var/log/debug
-
-echo -n 0 > /sys/module/bcm5974/parameters/debug

-Multi-touch (MT) Protocol
--------------------------
- Copyright (C) 2009 Henrik Rydberg
-
-
-Introduction
-------------
-
-In order to utilize the full power of the new multi-touch devices, a way to
-report detailed finger data to user space is needed. This document
-describes the multi-touch (MT) protocol which allows kernel drivers to
-report details for an arbitrary number of fingers.
-
-
-Usage
------
-
-Anonymous finger details are sent sequentially as separate packets of ABS
-events. Only the ABS_MT events are recognized as part of a finger
-packet. The end of a packet is marked by calling the input_mt_sync()
-function, which generates a SYN_MT_REPORT event. The end of multi-touch
-transfer is marked by calling the usual input_sync() function.
-
-A set of ABS_MT events with the desired properties is defined. The events
-are divided into categories, to allow for partial implementation. The
-minimum set consists of ABS_MT_TOUCH_MAJOR, ABS_MT_POSITION_X and
-ABS_MT_POSITION_Y, which allows for multiple fingers to be tracked. If the
-device supports it, the ABS_MT_WIDTH_MAJOR may be used to provide the size
-of the approaching finger. Anisotropy and direction may be specified with
-ABS_MT_TOUCH_MINOR, ABS_MT_WIDTH_MINOR and ABS_MT_ORIENTATION. Devices with
-more granular information may specify general shapes as blobs, i.e., as a
-sequence of rectangular shapes grouped together by an
-ABS_MT_BLOB_ID. Finally, the ABS_MT_TOOL_TYPE may be used to specify
-whether the touching tool is a finger or a pen or something else.
-
-
-Event Semantics
----------------
-
-The word "contact" is used to describe a tool which is in direct contact
-with the surface. A finger, a pen or a rubber all classify as contacts.
-
-ABS_MT_TOUCH_MAJOR
-
-The length of the major axis of the contact. The length should be given in
-surface units. If the surface has an X times Y resolution, the largest
-possible value of ABS_MT_TOUCH_MAJOR is sqrt(X^2 + Y^2), the diagonal.
-
-ABS_MT_TOUCH_MINOR
-
-The length, in surface units, of the minor axis of the contact. If the
-contact is circular, this event can be omitted.
-
-ABS_MT_WIDTH_MAJOR
-
-The length, in surface units, of the major axis of the approaching
-tool. This should be understood as the size of the tool itself. The
-orientation of the contact and the approaching tool are assumed to be the
-same.
-
-ABS_MT_WIDTH_MINOR
-
-The length, in surface units, of the minor axis of the approaching
-tool. Omit if circular.
-
-The above four values can be used to derive additional information about
-the contact. The ratio ABS_MT_TOUCH_MAJOR / ABS_MT_WIDTH_MAJOR approximates
-the notion of pressure. The fingers of the hand and the palm all have
-different characteristic widths [1].
-
-ABS_MT_ORIENTATION
-
-The orientation of the ellipse. The value should describe half a revolution
-clockwise around the touch center. The scale of the value is arbitrary, but
-zero should be returned for an ellipse aligned along the Y axis of the
-surface. As an example, an index finger placed straight onto the axis could
-return zero orientation, something negative when twisted to the left, and
-something positive when twisted to the right. This value can be omitted if
-the touching object is circular, or if the information is not available in
-the kernel driver.
-
-ABS_MT_POSITION_X
-
-The surface X coordinate of the center of the touching ellipse.
-
-ABS_MT_POSITION_Y
-
-The surface Y coordinate of the center of the touching ellipse.
-
-ABS_MT_TOOL_TYPE
-
-The type of approaching tool. A lot of kernel drivers cannot distinguish
-between different tool types, such as a finger or a pen. In such cases, the
-event should be omitted. The protocol currently supports MT_TOOL_FINGER and
-MT_TOOL_PEN [2].
-
-ABS_MT_BLOB_ID
-
-The BLOB_ID groups several packets together into one arbitrarily shaped
-contact. This is a low-level anonymous grouping, and should not be confused
-with the high-level contactID, explained below. Most kernel drivers will
-not have this capability, and can safely omit the event.
-
-
-Finger Tracking
----------------
-
-The kernel driver should generate an arbitrary enumeration of the set of
-anonymous contacts currently on the surface. The order in which the packets
-appear in the event stream is not important.
-
-The process of finger tracking, i.e., to assign a unique contactID to each
-initiated contact on the surface, is left to user space; preferably the
-multi-touch X driver [3]. In that driver, the contactID stays the same and
-unique until the contact vanishes (when the finger leaves the surface). The
-problem of assigning a set of anonymous fingers to a set of identified
-fingers is a euclidian bipartite matching problem at each event update, and
-relies on a sufficiently rapid update rate.
-
-Notes
------
-
-In order to stay compatible with existing applications, the data
-reported in a finger packet must not be recognized as single-touch
-events. In addition, all finger data must bypass input filtering,
-since subsequent events of the same type refer to different fingers.
-
-The first kernel driver to utilize the MT protocol is the bcm5974 driver,
-where examples can be found.
-
-[1] With the extension ABS_MT_APPROACH_X and ABS_MT_APPROACH_Y, the
-difference between the contact position and the approaching tool position
-could be used to derive tilt.
-[2] The list can of course be extended.
-[3] The multi-touch X driver is currently in the prototyping stage. At the
-time of writing (April 2009), the MT protocol is not yet merged, and the
-prototype implements finger matching, basic mouse support and two-finger
-scrolling. The project aims at improving the quality of current multi-touch
-functionality available in the synaptics X driver, and in addition
-implement more advanced gestures.

-Kernel CAPI Interface to Hardware Drivers
------------------------------------------
-
-1. Overview
-
-From the CAPI 2.0 specification:
-COMMON-ISDN-API (CAPI) is an application programming interface standard used
-to access ISDN equipment connected to basic rate interfaces (BRI) and primary
-rate interfaces (PRI).
-
-Kernel CAPI operates as a dispatching layer between CAPI applications and CAPI
-hardware drivers. Hardware drivers register ISDN devices (controllers, in CAPI
-lingo) with Kernel CAPI to indicate their readiness to provide their service
-to CAPI applications. CAPI applications also register with Kernel CAPI,
-requesting association with a CAPI device. Kernel CAPI then dispatches the
-application registration to an available device, forwarding it to the
-corresponding hardware driver. Kernel CAPI then forwards CAPI messages in both
-directions between the application and the hardware driver.
-
-Format and semantics of CAPI messages are specified in the CAPI 2.0 standard.
-This standard is freely available from http://www.capi.org.
-
-
-2. Driver and Device Registration
-
-CAPI drivers optionally register themselves with Kernel CAPI by calling the
-Kernel CAPI function register_capi_driver() with a pointer to a struct
-capi_driver. This structure must be filled with the name and revision of the
-driver, and optionally a pointer to a callback function, add_card(). The
-registration can be revoked by calling the function unregister_capi_driver()
-with a pointer to the same struct capi_driver.
-
-CAPI drivers must register each of the ISDN devices they control with Kernel
-CAPI by calling the Kernel CAPI function attach_capi_ctr() with a pointer to a
-struct capi_ctr before they can be used. This structure must be filled with
-the names of the driver and controller, and a number of callback function
-pointers which are subsequently used by Kernel CAPI for communicating with the
-driver. The registration can be revoked by calling the function
-detach_capi_ctr() with a pointer to the same struct capi_ctr.
-
-Before the device can be actually used, the driver must fill in the device
-information fields 'manu', 'version', 'profile' and 'serial' in the capi_ctr
-structure of the device, and signal its readiness by calling capi_ctr_ready().
-From then on, Kernel CAPI may call the registered callback functions for the
-device.
-
-If the device becomes unusable for any reason (shutdown, disconnect ...), the
-driver has to call capi_ctr_reseted(). This will prevent further calls to the
-callback functions by Kernel CAPI.
-
-
-3. Application Registration and Communication
-
-Kernel CAPI forwards registration requests from applications (calls to CAPI
-operation CAPI_REGISTER) to an appropriate hardware driver by calling its
-register_appl() callback function. A unique Application ID (ApplID, u16) is
-allocated by Kernel CAPI and passed to register_appl() along with the
-parameter structure provided by the application. This is analogous to the
-open() operation on regular files or character devices.
-
-After a successful return from register_appl(), CAPI messages from the
-application may be passed to the driver for the device via calls to the
-send_message() callback function. The CAPI message to send is stored in the
-data portion of an skb. Conversely, the driver may call Kernel CAPI's
-capi_ctr_handle_message() function to pass a received CAPI message to Kernel
-CAPI for forwarding to an application, specifying its ApplID.
-
-Deregistration requests (CAPI operation CAPI_RELEASE) from applications are
-forwarded as calls to the release_appl() callback function, passing the same
-ApplID as with register_appl(). After return from release_appl(), no CAPI
-messages for that application may be passed to or from the device anymore.
-
-
-4. Data Structures
-
-4.1 struct capi_driver
-
-This structure describes a Kernel CAPI driver itself. It is used in the
-register_capi_driver() and unregister_capi_driver() functions, and contains
-the following non-private fields, all to be set by the driver before calling
-register_capi_driver():
-
-char name[32]
- the name of the driver, as a zero-terminated ASCII string
-char revision[32]
- the revision number of the driver, as a zero-terminated ASCII string
-int (*add_card)(struct capi_driver *driver, capicardparams *data)
- a callback function pointer (may be NULL)
-
-
-4.2 struct capi_ctr
-
-This structure describes an ISDN device (controller) handled by a Kernel CAPI
-driver. After registration via the attach_capi_ctr() function it is passed to
-all controller specific lower layer interface and callback functions to
-identify the controller to operate on.
-
-It contains the following non-private fields:

- applications with the device
-
-u16 (*send_message)(struct capi_ctr *ctrlr, struct sk_buff *skb)
- pointer to a callback function for sending a CAPI message to the
- device
-
-char *(*procinfo)(struct capi_ctr *ctrlr)
- pointer to a callback function returning the entry for the device in
- the CAPI controller info table, /proc/capi/controller
-
-read_proc_t *ctr_read_proc
- pointer to the read_proc callback function for the device's proc file
- system entry, /proc/capi/controllers/; will be called with a
- pointer to the device's capi_ctr structure as the last (data) argument
-

- interworking branch is replaced with another code sequence at the

- stale interworking branch prediction. This results in Cortex-A8
- executing the new code sequence in the incorrect ARM or Thumb state.

- possible for a hazard condition intended for a cache line to instead
- be incorrectly associated with a different cache line. This false

- workaround disables the write-allocate mode for the L2 cache via the
- ACTLR register. Note that setting specific bits in the ACTLR register
- may not be available in non-secure mode.

-/*
- * This EDMA3 programming framework exposes two basic kinds of resource:
- *
- * Channel Triggers transfers, usually from a hardware event but
- * also manually or by "chaining" from DMA completions.
- * Each channel is coupled to a Parameter RAM (PaRAM) slot.
- *
- * Slot Each PaRAM slot holds a DMA transfer descriptor (PaRAM
- * "set"), source and destination addresses, a link to a
- * next PaRAM slot (if any), options for the transfer, and
- * instructions for updating those addresses. There are
- * more than twice as many slots as event channels.
- *
- * Each PaRAM set describes a sequence of transfers, either for one large
- * buffer or for several discontiguous smaller buffers. An EDMA transfer
- * is driven only from a channel, which performs the transfers specified
- * in its PaRAM slot until there are no more transfers. When that last
- * transfer completes, the "link" field may be used to reload the channel's
- * PaRAM slot with a new transfer descriptor.
- *
- * The EDMA Channel Controller (CC) maps requests from channels into physical
- * Transfer Controller (TC) requests when the channel triggers (by hardware
- * or software events, or by chaining). The two physical DMA channels provided
- * by the TCs are thus shared by many logical channels.
- *
- * DaVinci hardware also has a "QDMA" mechanism which is not currently
- * supported through this interface. (DSP firmware uses it though.)
