1* Marvell SoC pinctrl core driver for mpp2 3The pinctrl driver enables Marvell SoCs to configure the multi-purpose pins4(mpp) to a specific function. For each SoC family there is a SoC specific5driver using this core driver.6 7Please refer to pinctrl-bindings.txt in this directory for details of the8common pinctrl bindings used by client devices, including the meaning of the9phrase "pin configuration node".10 11A Marvell SoC pin configuration node is a node of a group of pins which can12be used for a specific device or function. Each node requires one or more13mpp pins or group of pins and a mpp function common to all pins.14 15Required properties for pinctrl driver:16- compatible: "marvell,<soc>-pinctrl"17 Please refer to each marvell,<soc>-pinctrl.txt binding doc for supported SoCs.18 19Required properties for pin configuration node:20- marvell,pins: string array of mpp pins or group of pins to be muxed.21- marvell,function: string representing a function to mux to for all22 marvell,pins given in this pin configuration node. The function has to be23 common for all marvell,pins. Please refer to marvell,<soc>-pinctrl.txt for24 valid pin/pin group names and available function names for each SoC.25 26Examples:27 28uart1: serial@12100 {29 compatible = "ns16550a";30 reg = <0x12100 0x100>;31 reg-shift = <2>;32 interrupts = <7>;33 34 pinctrl-0 = <&pmx_uart1_sw>;35 pinctrl-names = "default";36};37 38pinctrl: pinctrl@d0200 {39 compatible = "marvell,dove-pinctrl";40 reg = <0xd0200 0x14>, <0xd0440 0x04>, <0xd802c 0x08>;41 42 pmx_uart1_sw: pmx-uart1-sw {43 marvell,pins = "mpp_uart1";44 marvell,function = "uart1";45 };46};47
