Hi, This is the v5 of my Ingenic pinctrl / GPIO patch set. The pinctrl driver now probes its children devices without using the MFD subsystem; the GPIO driver now uses the 'reg' property to know the bank number.

This commit adds documentation for the devicetree bindings of the pinctrl-ingenic driver, which handles pin configuration and pin muxing of the Ingenic SoCs currently supported by the Linux kernel.
