		specified
- clocks:	a clock binding for the IMCLK input

Optional properties:

Example:

sd0: sd@ab000000 {
	compatible = "renesas,usdhi6rol0";
	reg = <0xab000000 0x200>;
	interrupts = <0 23 0x4
		      0 24 0x4
		      0 25 0x4>;
	interrupt-names = "card detect", "data", "SDIO";
	bus-width = <4>;
	max-frequency = <50000000>;
	cap-power-off-card;
	clocks = <&imclk>;
	vmmc-supply = <&vcc_sd0>;
	vqmmc-supply = <&vccq_sd0>;
