Add DT binding document to support these pins in GPIO mode via GPIO framework. Signed-off-by: Laxman Dewangan Acked-by: Rob Herring Acked-by: Linus Walleij --- This as part of the max77620 series and mfd patch are already applied. This can go in subsystem branch. Changes from V4: - Separate out from gpio driver Changes from V5/V6/V7: - None Changes from V8: - Collected Linus ack.
