From: Stefan Eichenberger <stefan.eichenberger@xxxxxxxxxxx> 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.
