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>;
};
