Input: elants_i2c - fix wake-on-touch

2015-12-19T00:21:43+00:00

When sending "SLEEP" command to the controller it ceases scanning
completely and is unable to wake the system up from sleep, so if it is
configured as a wakeup source we should simply configure interrupt for
wakeup and rely on idle logic within the controller to reduce power
consumption while it is not used.

Input: elan_i2c - set input device's vendor and product IDs

2015-12-15T19:35:55+00:00

Previously the "vendor" and "product" IDs for the elan_i2c driver simply
reported 0000.  This patch modifies the elan_i2c driver to include the
Elan vendor ID and the touchpad's product id under
input/input*/{vendor,product}.

Specifically, this is to allow us to apply a generic Elan gestures config
that will apply to all Elan touchpads on ChromeOS.  These configs  match to
input devices in various ways, but one major way is by matching on vendor
ID.  Adding this patch allows the default Elan touchpad config to be
applied to Elan touchpads in this kernel by matching on devices that have
vendor ID 04f3.

Note that product ID is also available via custom sysfs entry "product_id"
as well.

Input: atmel_mxt_ts - add maxtouch to I2C table for module autoload

2015-12-11T21:25:21+00:00

The Atmel maxtouch DT binding documents that the compatible string for
the device is "atmel,maxtouch" and the I2C core always reports a module
alias of the form i2c:alias where alias is the compatible string model:

$ grep MODALIAS /sys/devices/platform/12e00000.i2c/i2c-8/8-004b/uevent
MODALIAS=i2c:maxtouch

But there isn't maxtouch entry in the I2C device ID table so when the
i2c:maxtouch MODALIAS uevent is reported, kmod is not able to match the
alias with a module to load:

$ modinfo atmel_mxt_ts | grep alias
alias:          of:N*T*Catmel,maxtouch
alias:          i2c:mXT224
alias:          i2c:atmel_mxt_tp
alias:          i2c:atmel_mxt_ts
alias:          i2c:qt602240_ts

So add the maxtouch entry to the I2C device ID table to allow the module
to be autoloaded when the device is registered via OF.

Input: arizona-haptic - fix disabling of haptics device

2015-12-03T00:22:11+00:00

A small copy and paste error was preventing the haptics device being
disabled. This patch corrects the value written on disable.

Input: aiptek - fix crash on detecting device without endpoints

2015-12-02T17:35:41+00:00

The aiptek driver crashes in aiptek_probe() when a specially crafted USB
device without endpoints is detected. This fix adds a check that the device
has proper configuration expected by the driver. Also an error return value
is changed to more matching one in one of the error paths.

Input: atmel_mxt_ts - add generic platform data for Chromebooks

2015-12-02T17:35:40+00:00

Apparently people are installing generic Linux distributions not only on
Pixels but also on other Chromebooks. Unfortunately on all of them Atmel
parts assigned names ATML0000 and ATML0001, and do not carry any other
configuration data. So let's create generic instance of platform data that
should cover most of them (we assume that they will not be using T100
objects, since with those Google mapped BTN_LEFT onto a different GPIO, so
slightly different keymap would be needed, but I think we used parts with
T100 on ARM devices where we thankfully have DTS and can describe the
devices better).
