Before I get all carried away and start filling in all the data for this driver, I was hoping someone (or a few people) could review the basic design in case it requires changes to the data structures.
This driver is based on pinctrl-bcm2835.c as it seems to be similar in design. The pin controller on Wondermedia SoC's only allows each pin to either be a GPIO or to be its 'alternate' function. Functions cannot be remapped to any other pin. I have seperated out the data from the code as there are several SoC's to support and each has it's own variation of registers / pin layout. I borrowed this part of the design from the Tegra pinctrl driver.
