It has been successfully tested on Dove and Armada XP at the moment. Compared to the plat-orion driver, this new driver has the following added benefits: *) Support for Armada 370 and Armada XP *) It is integrated with the mvebu pinctrl driver so that GPIO pins are properly muxed, and the GPIO driver knows which GPIO pins are output-only or input-only. *) Properly placed in drivers/gpio *) More extensible mechanism to support platform differences. The plat-orion driver uses a simple mask-offset DT property, which works fine for Discovery MV78200 but not for Armada XP. The new driver uses different compatible strings to identify the different variants of the GPIO controllers.
