GPIO specifications in device tree
#2
I now understand that there is a difference between the sunxi pinctrl format and the gpio format that CS4270 is expecting. The gpio.txt document indicates that GPIOs are specified as a number and a flags value. SUNXI functions specify GPIOs as 6 different numbers of bank, # in bank, etc. How do I create a gpio node in the device tree that I can use to specify the reset is on PC11 (gpio 75) in the 2 cell format?
