Input: tm2-touchkey - acknowledge that setting brightness is a blocking call

2019-02-08T07:41:12Z

We need to access I2C bus when switching brightness, and that may block, therefore we have to set stmfts_brightness_set() as LED's brightness_set_blocking() method. Fixes: 72d1f2346ded ("Input: tm2-touchkey - add touchkey driver support for TM2") Acked-by: Andi Shyti Signed-off-by: Dmitry Torokhov

Input: tm2-touchkey - add support for aries touchkey variant

2019-01-07T19:49:42Z

The touchkey variant found on aries board is slighty different, it uses a fixed regulator and writes/read to the same place Signed-off-by: Jonathan Bakker Signed-off-by: Paweł Chmiel Reviewed-by: Rob Herring Signed-off-by: Dmitry Torokhov

Input: tm2-touchkey - allow specifying custom keycodes

2019-01-07T19:49:41Z

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. Signed-off-by: Jonathan Bakker Signed-off-by: Paweł Chmiel Signed-off-by: Dmitry Torokhov

Input: tm2-touchkey - correct initial brightness

2019-01-07T19:49:40Z

tm2-touchkey doesn't have brightness levels, but only on/off states, so replace LED_FULL with LED_ON. Signed-off-by: Jonathan Bakker Signed-off-by: Paweł Chmiel Signed-off-by: Dmitry Torokhov

Input: tm2-touchkey - add support for midas touchkey

2019-01-07T19:49:40Z

The touchkey on midas boards is almost identical. The only real difference is that it uses the same register for both keycode and base. Signed-off-by: Simon Shields Signed-off-by: Paweł Chmiel Reviewed-by: Rob Herring Signed-off-by: Dmitry Torokhov

Input: tm2-touchkey - use LEN_ON as boolean value instead of LED_FULL

2017-06-02T05:08:05Z

Commit 4e552c8cb5bc ("leds: add LED_ON brightness as boolean value") has introduced the LED_ON enumeration value that can be used instead of LED_FULL which has more of a linear value. Because the tm2-touchscreen doesn't have brightness levels, but it's a simple on/off led, use LED_ON instead of LED_FULL.

Input: keyboard - drop unnecessary calls to input_set_drvdata

2017-01-23T01:22:25Z

If there is no call to dev_get_drvdata() or input_get_drvdata(), the call to input_set_drvdata() is unnecessary and can be dropped. Signed-off-by: Guenter Roeck Signed-off-by: Dmitry Torokhov

Input: tm2-touchkey - add touchkey driver support for TM2

2017-01-18T22:50:23Z

This patch adds support for the TM2 touch key and led functionality. The driver interfaces with userspace through an input device and reports KEY_PHONE and KEY_BACK event types. LED brightness can be controlled by "/sys/class/leds/tm2-touchkey/brightness".
