| Tom Rini | 53633a8 | 2024-02-29 12:33:36 -0500 | [diff] [blame^] | 1 | * Renesas usdhi6rol0 SD/SDIO host controller |
| 2 | |
| 3 | Required properties: |
| 4 | |
| 5 | - compatible: must be |
| 6 | "renesas,usdhi6rol0" |
| 7 | - interrupts: 3 interrupts, named "card detect", "data" and "SDIO" must be |
| 8 | specified |
| 9 | - clocks: a clock binding for the IMCLK input |
| 10 | |
| 11 | Optional properties: |
| 12 | |
| 13 | - vmmc-supply: a phandle of a regulator, supplying Vcc to the card |
| 14 | - vqmmc-supply: a phandle of a regulator, supplying VccQ to the card |
| 15 | - pinctrl-names: Can contain a "default" entry and a "state_uhs" |
| 16 | entry. The state_uhs entry is used together with the default |
| 17 | entry when the board requires distinct settings for UHS speeds. |
| 18 | |
| 19 | - pinctrl-N: One property for each name listed in pinctrl-names, see |
| 20 | ../pinctrl/pinctrl-bindings.txt. |
| 21 | |
| 22 | Additionally any standard mmc bindings from mmc.txt can be used. |
| 23 | |
| 24 | Example: |
| 25 | |
| 26 | sd0: sd@ab000000 { |
| 27 | compatible = "renesas,usdhi6rol0"; |
| 28 | reg = <0xab000000 0x200>; |
| 29 | interrupts = <0 23 0x4 |
| 30 | 0 24 0x4 |
| 31 | 0 25 0x4>; |
| 32 | interrupt-names = "card detect", "data", "SDIO"; |
| 33 | bus-width = <4>; |
| 34 | max-frequency = <50000000>; |
| 35 | cap-power-off-card; |
| 36 | clocks = <&imclk>; |
| 37 | vmmc-supply = <&vcc_sd0>; |
| 38 | vqmmc-supply = <&vccq_sd0>; |
| 39 | }; |
