From: Alexey Minnekhanov <[email protected]> In Linux driver, depending on which GDSC flags are set, a different status register is checked when powering it on/off. And on top of that, a different bit inside that register is tested.
As a first step towards adding behaviour variation, import GDSC flags from Linux driver. Even though only POLL_CFG_GDSCR is the important one here, add all flags in order to make it easier to compare which flags are needed for which GDSC, making the porting process easier.
