The at91 pinctrl driver uses "atmel,at91rm9200-gpio" compatible string to find the number of active GPIO banks and identify the pinmux nodes. "atmel,at91sam9x5-gpio" and "microchip,sam9x60-gpio" have additional registers to handle drive-strength, slew-rate, pull-down to drive the pinmux configs. The new compatible string "microchip,sam9x7-gpio" is added.
