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