[PATCH v3 2/3] Input: edt-ft5x06 - Set wake/reset values on resume/suspend

From: Mylène Josserand <hidden>
Date: 2018-07-18 18:27:42
Also in: linux-arm-kernel, linux-devicetree, lkml
Subsystem: input (keyboard, mouse, joystick, touchscreen) drivers, the rest · Maintainers: Dmitry Torokhov, Linus Torvalds

On resume and suspend, set the value of wake and reset gpios
to be sure that we are in a know state after suspending/resuming.
