| Device Tree Bindings for the Arasan SDHCI Controller |
| |
| The bindings follow the mmc[1], clock[2], interrupt[3] and phy[4] bindings. |
| Only deviations are documented here. |

| Required Properties: |
| - compatible: Compatibility string. Must be 'arasan,sdhci-8.9a' or |
| 'arasan,sdhci-4.9a' or 'arasan,sdhci-5.1' |
| - reg: From mmc bindings: Register location and length. |
| - clocks: From clock bindings: Handles to clock inputs. |
| - clock-names: From clock bindings: Tuple including "clk_xin" and "clk_ahb" |
| - interrupts: Interrupt specifier |
| - interrupt-parent: Phandle for the interrupt controller that services |
| interrupts for this device. |
| |
| Required Properties for "arasan,sdhci-5.1": |
| - phys: From PHY bindings: Phandle for the Generic PHY for arasan. |
| - phy-names: MUST be "phy_arasan". |
| |
| Example: |
| sdhci@e0100000 { |
| compatible = "arasan,sdhci-8.9a"; |
| reg = <0xe0100000 0x1000>; |
| clock-names = "clk_xin", "clk_ahb"; |
| clocks = <&clkc 21>, <&clkc 32>; |
| interrupt-parent = <&gic>; |
| interrupts = <0 24 4>; |
| } ; |
| |
| sdhci@e2800000 { |
| compatible = "arasan,sdhci-5.1"; |
| reg = <0xe2800000 0x1000>; |
| clock-names = "clk_xin", "clk_ahb"; |
| clocks = <&cru 8>, <&cru 18>; |
| interrupt-parent = <&gic>; |
| interrupts = <0 24 4>; |
| phys = <&emmc_phy>; |
| phy-names = "phy_arasan"; |
| } ; |
