* STMicroelectronics sdhci-st MMC/SD controller This file documents the differences between the core properties in Documentation/devicetree/bindings/mmc/mmc.txt and the properties used by the sdhci-st driver. Required properties: - compatible : Must be "st,sdhci" - clock-names : Should be "mmc" See: Documentation/devicetree/bindings/resource-names.txt - clocks : Phandle of the clock used by the sdhci controler See: Documentation/devicetree/bindings/clock/clock-bindings.txt Optional properties: - non-removable: non-removable slot See: Documentation/devicetree/bindings/mmc/mmc.txt - bus-width: Number of data lines See: Documentation/devicetree/bindings/mmc/mmc.txt Example: mmc0: sdhci@fe81e000 { compatible = "st,sdhci"; status = "disabled"; reg = <0xfe81e000 0x1000>; interrupts = ; interrupt-names = "mmcirq"; pinctrl-names = "default"; pinctrl-0 = <&pinctrl_mmc0>; clock-names = "mmc"; clocks = <&clk_s_a1_ls 1>; bus-width = <8> };
