1	* Marvell SoC pinctrl core driver for mpp
2	
3	The pinctrl driver enables Marvell SoCs to configure the multi-purpose pins
4	(mpp) to a specific function. For each SoC family there is a SoC specific
5	driver using this core driver.
6	
7	Please refer to pinctrl-bindings.txt in this directory for details of the
8	common pinctrl bindings used by client devices, including the meaning of the
9	phrase "pin configuration node".
10	
11	A Marvell SoC pin configuration node is a node of a group of pins which can
12	be used for a specific device or function. Each node requires one or more
13	mpp pins or group of pins and a mpp function common to all pins.
14	
15	Required properties for pinctrl driver:
16	- compatible: "marvell,<soc>-pinctrl"
17	  Please refer to each marvell,<soc>-pinctrl.txt binding doc for supported SoCs.
18	
19	Required 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 all
22	    marvell,pins given in this pin configuration node. The function has to be
23	    common for all marvell,pins. Please refer to marvell,<soc>-pinctrl.txt for
24	    valid pin/pin group names and available function names for each SoC.
25	
26	Examples:
27	
28	uart1: 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	
38	pinctrl: 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	};
