1Properties for the MDIO bus multiplexer/glue of Amlogic G12a SoC family.
2
3This is a special case of a MDIO bus multiplexer. It allows to choose between
4the internal mdio bus leading to the embedded 10/100 PHY or the external
5MDIO bus.
6
7Required properties in addition to the generic multiplexer properties:
8- compatible : amlogic,g12a-mdio-mux
9- reg: physical address and length of the multiplexer/glue registers
10- clocks: list of clock phandle, one for each entry clock-names.
11- clock-names: should contain the following:
12  * "pclk"   : peripheral clock.
13  * "clkin0" : platform crytal
14  * "clkin1" : SoC 50MHz MPLL

16Example :

19	compatible = "amlogic,g12a-mdio-mux";
20	reg = <0x0 0x4c000 0x0 0xa4>;
21	clocks = <&clkc CLKID_ETH_PHY>,
22		 <&xtal>,
23		 <&clkc CLKID_MPLL_5OM>;
24	clock-names = "pclk", "clkin0", "clkin1";
25	mdio-parent-bus = <&mdio0>;
26	#address-cells = <1>;
27	#size-cells = <0>;
28
29	ext_mdio: mdio@0 {
30		reg = <0>;
31		#address-cells = <1>;
32		#size-cells = <0>;
33	};
34
35	int_mdio: mdio@1 {
36		reg = <1>;
37		#address-cells = <1>;
38		#size-cells = <0>;

43			interrupts = <GIC_SPI 9 IRQ_TYPE_LEVEL_HIGH>;
44			reg = <8>;
45			max-speed = <100>;
