1* Renesas usdhi6rol0 SD/SDIO host controller
2
3Required 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
11Optional 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
22Additionally any standard mmc bindings from mmc.txt can be used.

32	interrupt-names = "card detect", "data", "SDIO";
33	bus-width = <4>;
