Subject: [PATCH RESEND v3 0/2] Add a property to turn off the max touch controller in suspend mode
Date: Fri,  9 Feb 2024 11:50:10 +0100

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.

Resend v3:
- Previously I messed up the series because send-email crashed. This is
  a resend of the original series:
