  1. Device Tree Bindings for the Arasan SDHCI Controller
  2. The bindings follow the mmc[1], clock[2] and interrupt[3] bindings. Only
  3. deviations are documented here.
  4. [1] Documentation/devicetree/bindings/mmc/mmc.txt
  5. [2] Documentation/devicetree/bindings/clock/clock-bindings.txt
  6. [3] Documentation/devicetree/bindings/interrupt-controller/interrupts.txt
  7. Required Properties:
  8. - compatible: Compatibility string. Must be 'arasan,sdhci-8.9a' or
  9. 'arasan,sdhci-4.9a' or 'arasan,sdhci-5.1'
  10. - reg: From mmc bindings: Register location and length.
  11. - clocks: From clock bindings: Handles to clock inputs.
  12. - clock-names: From clock bindings: Tuple including "clk_xin" and "clk_ahb"
  13. - interrupts: Interrupt specifier
  14. - interrupt-parent: Phandle for the interrupt controller that services
  15. interrupts for this device.
  16. Example:
  17. sdhci@e0100000 {
  18. compatible = "arasan,sdhci-8.9a";
  19. reg = <0xe0100000 0x1000>;
  20. clock-names = "clk_xin", "clk_ahb";
  21. clocks = <&clkc 21>, <&clkc 32>;
  22. interrupt-parent = <&gic>;
  23. interrupts = <0 24 4>;
  24. } ;
