* Renesas usdhi6rol0 SD/SDIO host controller
Required properties:
- compatible: must be
- interrupts: 3 interrupts, named "card detect", "data" and "SDIO" must be
- clocks: a clock binding for the IMCLK input
Optional properties:
- vmmc-supply: a phandle of a regulator, supplying Vcc to the card
- vqmmc-supply: a phandle of a regulator, supplying VccQ to the card
- pinctrl-names: Can contain a "default" entry and a "state_uhs"
entry. The state_uhs entry is used together with the default
