+* Renesas usdhi6rol0 SD/SDIO host controller
+
+Required properties:
+
+- compatible:   must be
+                "renesas,usdhi6rol0"
+- interrupts:   3 interrupts, named "card detect", "data" and "SDIO" must be
+                specified
+- 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
+
+Additionally any standard mmc bindings from mmc.txt can be used.
+
+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>;
