A nuvoton,*-gcr node is present in nuvoton-common-npcm7xx.dtsi and will be added to nuvoton-wpcm450.dtsi. It is necessary for the NPCM7xx and WPCM450 pinctrl drivers, and may later be used to retrieve SoC model and version information. This patch adds a binding to describe this node.

How is this a simple-mfd? There are no child nodes.
