- * 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 = <GIC_SPI 127 IRQ_TYPE_NONE>;
- interrupt-names = "mmcirq";
- pinctrl-names = "default";
- pinctrl-0 = <&pinctrl_mmc0>;
- clock-names = "mmc";
- clocks = <&clk_s_a1_ls 1>;
- bus-width = <8>
- };
