Kernel-4.18.0-80.el8_usdhi6rol0

• 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

• pinctrl-names: Can contain a “default” entry and a “state_uhs”

             entry. The state_uhs entry is used together with the default
             entry when the board requires distinct settings for UHS speeds.
  

• pinctrl-N: One property for each name listed in pinctrl-names, see

         ../pinctrl/pinctrl-bindings.txt.
  

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>;
};
