-Device properties:
-=================
-Normally, userspace sets up an input device based on the data it emits,
-i.e., the event types. In the case of two devices emitting the same event
-types, additional information can be provided in the form of device
-properties.
-
-INPUT_PROP_DIRECT + INPUT_PROP_POINTER:
---------------------------------------
-The INPUT_PROP_DIRECT property indicates that device coordinates should be
-directly mapped to screen coordinates (not taking into account trivial
-transformations, such as scaling, flipping and rotating). Non-direct input
-devices require non-trivial transformation, such as absolute to relative
-transformation for touchpads. Typical direct input devices: touchscreens,
-drawing tablets; non-direct devices: touchpads, mice.
-
-The INPUT_PROP_POINTER property indicates that the device is not transposed
-on the screen and thus requires use of an on-screen pointer to trace user's
-movements. Typical pointer devices: touchpads, tablets, mice; non-pointer
-device: touchscreen.
-
-If neither INPUT_PROP_DIRECT or INPUT_PROP_POINTER are set, the property is
-considered undefined and the device type should be deduced in the
-traditional way, using emitted event types.
-
-INPUT_PROP_BUTTONPAD:
---------------------
-For touchpads where the button is placed beneath the surface, such that
-pressing down on the pad causes a button click, this property should be
-set. Common in clickpad notebooks and macbooks from 2009 and onwards.
-
-Originally, the buttonpad property was coded into the bcm5974 driver
-version field under the name integrated button. For backwards
-compatibility, both methods need to be checked in userspace.
-
-INPUT_PROP_SEMI_MT:
-------------------
-Some touchpads, most common between 2008 and 2011, can detect the presence
-of multiple contacts without resolving the individual positions; only the
-number of contacts and a rectangular shape is known. For such
-touchpads, the semi-mt property should be set.
-
-Depending on the device, the rectangle may enclose all touches, like a
-bounding box, or just some of them, for instance the two most recent
-touches. The diversity makes the rectangle of limited use, but some
-gestures can normally be extracted from it.
-
-If INPUT_PROP_SEMI_MT is not set, the device is assumed to be a true MT
-device.

- here are those that are setting up dedicated Ethernet WWW/FTP
- servers, or users that have one of the various bus mice instead of a
- serial mouse and don't intend to use their machine's standard serial
- port for anything. (Note that the Cyclades and Stallion multi
- serial port drivers do not need this driver built in for them to
- work.)

- BTW1: If you have a mouseman serial mouse which is not recognized by
- the X window system, try running gpm first.
-
- BTW2: If you intend to use a software modem (also called Winmodem)
- under Linux, forget it. These modems are crippled and require

- mode). This could be useful if some terminal or printer is connected
- to that serial port.
-
- Even if you say Y here, the currently visible virtual console
- (/dev/tty0) will still be used as the system console by default, but
- you can alter that using a kernel command line option such as
- "console=ttyS1". (Try "man bootparam" or see the documentation of
- your boot loader (grub or lilo or loadlin) about how to pass options
- to the kernel at boot time.)
-
- If you don't have a VGA card installed and you say Y here, the
- kernel will automatically use the first serial line, /dev/ttyS0, as
- system console.
-
- You can set that using a kernel command line option such as
- "console=uart8250,io,0x3f8,9600n8"

+config SERIAL_8250
+ tristate "8250/16550 and compatible serial support"
+ select SERIAL_CORE
+ ---help---
+ This selects whether you want to include the driver for the standard
+ serial ports. The standard answer is Y. People who might say N
+ here are those that are setting up dedicated Ethernet WWW/FTP
+ servers, or users that have one of the various bus mice instead of a
+ serial mouse and don't intend to use their machine's standard serial
+ port for anything. (Note that the Cyclades and Stallion multi
+ serial port drivers do not need this driver built in for them to
+ work.)
+
+ To compile this driver as a module, choose M here: the
+ module will be called 8250.
+ [WARNING: Do not compile this driver as a module if you are using
+ non-standard serial ports, since the configuration information will
+ be lost when the driver is unloaded. This limitation may be lifted
+ in the future.]
+
+ BTW1: If you have a mouseman serial mouse which is not recognized by
+ the X window system, try running gpm first.
+
+ BTW2: If you intend to use a software modem (also called Winmodem)
+ under Linux, forget it. These modems are crippled and require
+ proprietary drivers which are only available under Windows.
+
+ Most people will say Y or M here, so that they can use serial mice,
+ modems and similar devices connecting to the standard serial ports.

+ bool "Console on 8250/16550 and compatible serial port"
+ depends on SERIAL_8250=y
+ select SERIAL_CORE_CONSOLE
+ ---help---
+ If you say Y here, it will be possible to use a serial port as the
+ system console (the system console is the device which receives all
+ kernel messages and warnings and which allows logins in single user
+ mode). This could be useful if some terminal or printer is connected
+ to that serial port.
+
+ Even if you say Y here, the currently visible virtual console
+ (/dev/tty0) will still be used as the system console by default, but
+ you can alter that using a kernel command line option such as
+ "console=ttyS1". (Try "man bootparam" or see the documentation of
+ your boot loader (grub or lilo or loadlin) about how to pass options
+ to the kernel at boot time.)
+
+ If you don't have a VGA card installed and you say Y here, the
+ kernel will automatically use the first serial line, /dev/ttyS0, as
+ system console.
+
+ You can set that using a kernel command line option such as
+ "console=uart8250,io,0x3f8,9600n8"
+ "console=uart8250,mmio,0xff5e0000,115200n8".
+ and it will switch to normal serial console when the corresponding
+ port is ready.
+ "earlycon=uart8250,io,0x3f8,9600n8"
+ "earlycon=uart8250,mmio,0xff5e0000,115200n8".
