This patches adds support for Aries (Samsung i9000) and Midsa (Samsung S3)
based devices to TM2 Touchkey driver.
Changes from v1:
- Added Reviewed-by to some patches
- Use ints for keycodes (they could be bigger than 255)
- Droped separate name changes
- Added missing const in few places
- Removed redundant cast
Jonathan Bakker (5):
Input: tm2-touchkey: Correct initial brightness
Input: tm2-touchkey: Allow specifying custom keycodes
Input: dt-bindings: tm2-touchkey: Document new keycodes property
Input: tm2-touchkey: Add support for aries touchkey variant
Input: dt-bindings: tm2-touchkey: Add support for aries touchkey
Simon Shields (2):
Input: tm2-touchkey: Add support for midas touchkey
Input: dt-bindings: tm2-touchkey: Add support for midas touchkey

Tm2-touchkey don't have brightness levels, but only on/off states,
so replace LED_FULL with LED_ON.

The touchkey on midas boards is almost identical.
The only real difference is that it uses the same register for both
keycode and base.

Not all devices use the same keycodes in the same order,
so add possibility to define keycodes for buttons present
on actual hardware.
If keycodes property is not present, we assume that device has
at least MENU and BACK keys.
