0001 * Renesas usdhi6rol0 SD/SDIO host controller
0002
0003 Required properties:
0004
0005 - compatible: must be
0006 "renesas,usdhi6rol0"
0007 - interrupts: 3 interrupts, named "card detect", "data" and "SDIO" must be
0008 specified
0009 - clocks: a clock binding for the IMCLK input
0010
0011 Optional properties:
0012
0013 - vmmc-supply: a phandle of a regulator, supplying Vcc to the card
0014 - vqmmc-supply: a phandle of a regulator, supplying VccQ to the card
0015 - pinctrl-names: Can contain a "default" entry and a "state_uhs"
0016 entry. The state_uhs entry is used together with the default
0017 entry when the board requires distinct settings for UHS speeds.
0018
0019 - pinctrl-N: One property for each name listed in pinctrl-names, see
0020 ../pinctrl/pinctrl-bindings.txt.
0021
0022 Additionally any standard mmc bindings from mmc.txt can be used.

0024 Example:
0025
0026 sd0: sd@ab000000 {
0027 compatible = "renesas,usdhi6rol0";
0028 reg = <0xab000000 0x200>;
0029 interrupts = <0 23 0x4
0030 0 24 0x4
0031 0 25 0x4>;
0032 interrupt-names = "card detect", "data", "SDIO";
0033 bus-width = <4>;
0034 max-frequency = <50000000>;
0035 cap-power-off-card;
0036 clocks = <&imclk>;
0037 vmmc-supply = <&vcc_sd0>;
0038 vqmmc-supply = <&vccq_sd0>;
0039 };
