-Subject: [PATCH] MIPS: ath79: fix GPIO function selection for AR934x SoCs
-
-GPIO function selection is not working on the AR934x
-SoCs because the offset of the function selection
-register is different on those.
-
-Add a helper routine which returns the correct
-register address based on the SoC type, and use
-that in the 'ath79_gpio_function_*' routines.
