 Required properties for the root node:
  - compatible: Should be one of the following
 	       "mediatek,mt7622-pinctrl" for MT7622 SoC
+	       "mediatek,mt7629-pinctrl" for MT7629 SoC
  - reg: offset and length of the pinctrl space
 
  - gpio-controller: Marks the device node as a GPIO controller.
