1	* Renesas usdhi6rol0 SD/SDIO host controller
2	
3	Required properties:
4	
5	- compatible:	must be
6			"renesas,usdhi6rol0"
7	- interrupts:	3 interrupts, named "card detect", "data" and "SDIO" must be
8			specified
9	- clocks:	a clock binding for the IMCLK input
10	
11	Optional properties:
12	
13	- vmmc-supply:	a phandle of a regulator, supplying Vcc to the card
14	- vqmmc-supply:	a phandle of a regulator, supplying VccQ to the card
15	- pinctrl-names: Can contain a "default" entry and a "state_uhs"
16	                 entry. The state_uhs entry is used together with the default
17	                 entry when the board requires distinct settings for UHS speeds.
18	
19	- pinctrl-N: One property for each name listed in pinctrl-names, see
20	             ../pinctrl/pinctrl-bindings.txt.
21	
22	Additionally any standard mmc bindings from mmc.txt can be used.
23	
24	Example:
25	
26	sd0: sd@ab000000 {
27		compatible = "renesas,usdhi6rol0";
28		reg = <0xab000000 0x200>;
29		interrupts = <0 23 0x4
30			      0 24 0x4
31			      0 25 0x4>;
32		interrupt-names = "card detect", "data", "SDIO";
33		bus-width = <4>;
34		max-frequency = <50000000>;
35		cap-power-off-card;
36		clocks = <&imclk>;
37		vmmc-supply = <&vcc_sd0>;
38		vqmmc-supply = <&vccq_sd0>;
39	};
