Required properties: - #address-cells : should be 1. - #size-cells : should be 1. - compatible : "nuvoton,npcm750-pinctrl" for Poleg NPCM7XX. - ranges : defines mapping ranges between pin controller node (parent) to GPIO bank node (children). === GPIO Bank Subnode === The NPCM7XX has 8 GPIO Banks each GPIO bank supports 32 GPIO. Required GPIO Bank subnode-properties: - reg : specifies physical base address and size of the GPIO bank registers. - gpio-controller : Marks the device node as a GPIO controller. - #gpio-cells : Must be <2>. The first cell is the gpio pin number and the second cell is used for optional parameters. - interrupts : contain the GPIO bank interrupt with flags for falling edge. - gpio-ranges : defines the range of pins managed by the GPIO bank controller. For example, GPIO bank subnodes like the following: gpio0: gpio@f0010000 { gpio-controller; #gpio-cells = <2>; reg = <0x0 0x80>; interrupts = <GIC_SPI 116 IRQ_TYPE_LEVEL_HIGH>; gpio-ranges = <&pinctrl 0 0 32>; }; === Pin Mux Subnode === - pin: A string containing the name of the pin An array of strings, each string containing the name of a pin. These pin are used for selecting pin configuration.
