This patch adds support for the GPIO/pinmux controller found on the VIA VT8500 and Wondermedia WM8xxx-series SoCs. Each pin within the controller is capable of operating as a GPIO or as an alternate function. The pins are numbered according to their control bank/bit so that if new pins are added, the existing numbering is maintained. All currently supported SoCs are included: VT8500, WM8505, WM8650, WM8750 and WM8850.
