[PATCH v3 0/2] Add a property to turn off the max touch controller in suspend mode

[Stefan Eichenberger]

Our hardware has a shared regulator that powers various peripherals such
as the display, touch, USB hub, etc. Since the Maxtouch controller
doesn't currently allow it to be turned off, this regulator has to stay
on in suspend mode. This increases the overall power consumption. In
order to turn off the controller when the system goes into suspend mode,
this series adds a device tree property to the maxtouch driver that
allows the controller to be turned off completely and ensurs that it can
resume from the power off state.

Changes since v2:
- Add Reviewed-by tags from Linus and Krzysztof to the dt-bindings patch

Changes since v1:
- Rename the property and change the description (Krzysztof, Linus,
Dmitry, Conor)

Stefan Eichenberger (2):
  dt-bindings: input: atmel,maxtouch: add poweroff-sleep property
  Input: atmel_mxt_ts - support poweroff in suspend
