Good start! Especially that you use GPIOLIB_IRQCHIP. But this (as discussed earlier) should select GENERIC_PINCONF Stopping review here so you can reengineer it a bit using GENERIC_PINCONF for next submission. Also think about pinmux in single registers, whether you want to do this with a single value for a register or using strings to identify groups and functions.
