There seem to be 3 different IP blocks for 3 separate banks of GPIOs in the iProc chips. I've dropped everything except support for the Chip Common A GPIO controller because the other blocks actually seem to be supportable with other drivers. The driver itself is halfway between pinctrl-nsp-gpio.c and pinctrl-iproc-gpio.c.
