Subject: [PATCH v5 3/4] dt-bindings: input: atmel,maxtouch: add poweroff-sleep property
From: Stefan Eichenberger <stefan.eichenberger@...adex.com>
Add a new property to indicate that the device should power off rather
than use deep sleep. Deep sleep is a feature of the controller that
expects the controller to remain powered in suspend. However, if a
display shares its regulator with the touch controller, we may want to
do a power off so that the display and touch controller do not use any
power.
