* 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>;
|
|
};
