Input: atmel_mxt_ts - add missing compatible strings to OF device table

2018-05-01T22:51:15+00:00

Commit af503716ac14 ("i2c: core: report OF style module alias for devices
registered via OF") fixed how the I2C core reports the module alias when
devices are registered via OF.

But the atmel_mxt_ts driver only has an "atmel,maxtouch" compatible in its
OF device ID table, so if a Device Tree is using a different one, autoload
won't be working for the module (the matching works because the I2C device
ID table is used as a fallback).

So add compatible strings for each of the entries in the I2C device table.

Input: gpio-keys - add support for wakeup event action

2018-03-14T17:13:22+00:00

Add support for specifying event actions to trigger wakeup when using
the gpio-keys input device as a wakeup source.

This would allow the device to configure when to wakeup the system. For
example a gpio-keys input device for pen insert, may only want to wakeup
the system when ejecting the pen.

 - Convert to use memblock_virt_alloc in DT code which supports
   bootmem arches. With this we can remove the arch specific
   early_init_dt_alloc_memory_arch() functions.

 - Enable running the DT unittests on UML

 - Use SPDX license tags on DT files

 - Fix early FDT kconfig ifdef logic

Input: mms114 - drop platform data and use generic APIs

2018-01-26T19:27:23+00:00

The MMS114 platform data has no in-tree users, so drop it.

Switch to using the standard touchscreen properties via
touchscreen_parse_properties(), and move the old DT parsing code
to use device_property_*() APIs.

Finally, use touchscreen_report_pos to report x/y coordinates
and drop the custom x/y inversion code.

Input: silead - add support for capactive home button found on some x86 tablets

2018-01-10T00:38:06+00:00

On some x86 tablets with a silead touchscreen the windows logo on the
front is a capacitive home button. Touching this button results in a touch
with bits 12-15 of the Y coordinates set, while normally only the lower 12
are used.

Detect this and report a KEY_LEFTMETA press when this happens. Note for
now we only respond to the Y coordinate bits 12-15 containing 0x01, on some
tablets *without* a capacative button I've noticed these bits containing
0x04 when crossing the edges of the screen.
