| |
| 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 |
| - pinctrl-names: Can contain a "default" entry and a "state_uhs" |
| entry. The state_uhs entry is used together with the default |

| |
| 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>; |
| }; |
