2016-10-03Input: ektf2127 - mark PM functions as __maybe_unusedArnd Bergmann
The newly added ektf2127 driver uses the SIMPLE_DEV_PM_OPS macro to conditionally refer to the resume/suspend functions, which causes a warning when CONFIG_PM_SLEEP is disabled: drivers/input/touchscreen/ektf2127.c:168:12: error: 'ektf2127_resume' defined but not used [-Werror=unused-function] drivers/input/touchscreen/ektf2127.c:156:12: error: 'ektf2127_suspend' defined but not used [-Werror=unused-function] We could either put these functions inside of an #ifdef or add __maybe_unused annotations. This uses the second approach, which is generally more foolproof.

2016-09-26Input: add support for Elan eKTF2127 touchscreen controllerSiebren Vroegindeweij
This adds a driver for the Elan eKTF2127 touchscreen controller, which speaks an i2c protocol which is distinctly different from the already supported eKTH controllers.
