  1. * STMicroelectronics sdhci-st MMC/SD controller
  2. This file documents the differences between the core properties in
  3. Documentation/devicetree/bindings/mmc/mmc.txt and the properties
  4. used by the sdhci-st driver.
  5. Required properties:
  6. - compatible : Must be "st,sdhci"
  7. - clock-names : Should be "mmc"
  8. See: Documentation/devicetree/bindings/resource-names.txt
  9. - clocks : Phandle of the clock used by the sdhci controler
  10. See: Documentation/devicetree/bindings/clock/clock-bindings.txt
  11. Optional properties:
  12. - non-removable: non-removable slot
  13. See: Documentation/devicetree/bindings/mmc/mmc.txt
  14. - bus-width: Number of data lines
  15. See: Documentation/devicetree/bindings/mmc/mmc.txt
  16. Example:
  17. mmc0: sdhci@fe81e000 {
  18. compatible = "st,sdhci";
  19. status = "disabled";
  20. reg = <0xfe81e000 0x1000>;
  21. interrupts = <GIC_SPI 127 IRQ_TYPE_NONE>;
  22. interrupt-names = "mmcirq";
  23. pinctrl-names = "default";
  24. pinctrl-0 = <&pinctrl_mmc0>;
  25. clock-names = "mmc";
  26. clocks = <&clk_s_a1_ls 1>;
  27. bus-width = <8>
  28. };
