From: David Daney <david.daney@xxxxxxxxxx> Just as gpiod_get() automatically interprets the OF_GPIO_ACTIVE_LOW flag from the device tree, add handling for OF_GPIO_OPEN_DRAIN and OF_GPIO_OPEN_SOURCE. This keeps the details of handling open-drain GPIOs in the core GPIO code, and out of the individual drivers.
