linux-next/drivers/pinctrl/vt8500/pinctrl-wm8505.c
Tony Prisk 170c6152ae pinctrl: gpio: vt8500: Add pincontrol driver for arch-vt8500 
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.
