Only deviations are documented here. [1] Documentation/devicetree/bindings/mmc/mmc.txt [2] Documentation/devicetree/bindings/clock/clock-bindings.txt [3] Documentation/devicetree/bindings/interrupt-controller/interrupts.txt [4] Documentation/devicetree/bindings/phy/phy-bindings.txt Required Properties: - compatible: Compatibility string. One of: - "arasan,sdhci-8.9a": generic Arasan SDHCI 8.9a PHY - "arasan,sdhci-4.9a": generic Arasan SDHCI 4.9a PHY - "arasan,sdhci-5.1": generic Arasan SDHCI 5.1 PHY - "rockchip,rk3399-sdhci-5.1", "arasan,sdhci-5.1": rk3399 eMMC PHY For this device it is strongly suggested to include arasan,soc-ctl-syscon. - "xlnx,zynqmp-8.9a": ZynqMP SDHCI 8.9a PHY For this device it is strongly suggested to include clock-output-names and #clock-cells. - "xlnx,versal-8.9a": Versal SDHCI 8.9a PHY For this device it is strongly suggested to include clock-output-names and #clock-cells. - "ti,am654-sdhci-5.1", "arasan,sdhci-5.1": TI AM654 MMC PHY Note: This binding has been deprecated and moved to [5]. - "intel,lgm-sdhci-5.1-emmc", "arasan,sdhci-5.1": Intel LGM eMMC PHY For this device it is strongly suggested to include arasan,soc-ctl-syscon. - "intel,lgm-sdhci-5.1-sdxc", "arasan,sdhci-5.1": Intel LGM SDXC PHY For this device it is strongly suggested to include arasan,soc-ctl-syscon. - "intel,keembay-sdhci-5.1-emmc", "arasan,sdhci-5.1": Intel Keem Bay eMMC For this device it is strongly suggested to include arasan,soc-ctl-syscon. - "intel,keembay-sdhci-5.1-sd": Intel Keem Bay SD controller For this device it is strongly suggested to include arasan,soc-ctl-syscon. - "intel,keembay-sdhci-5.1-sdio": Intel Keem Bay SDIO controller For this device it is strongly suggested to include arasan,soc-ctl-syscon. [5] Documentation/devicetree/bindings/mmc/sdhci-am654.txt - 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 Required Properties for "arasan,sdhci-5.1": - phys: From PHY bindings: Phandle for the Generic PHY for arasan. - phy-names: MUST be "phy_arasan". Optional Properties: - arasan,soc-ctl-syscon: A phandle to a syscon device (see ../mfd/syscon.txt) used to access core corecfg registers. Offsets of registers in this syscon are determined based on the main compatible string for the device. - clock-output-names: If specified, this will be the name of the card clock which will be exposed by this device. Required if #clock-cells is specified. - #clock-cells: If specified this should be the value <0> or <1>. With this property in place we will export one or two clocks representing the Card Clock. These clocks are expected to be consumed by our PHY. - xlnx,fails-without-test-cd: when present, the controller doesn't work when the CD line is not connected properly, and the line is not connected properly. Test mode can be used to force the controller to function. - xlnx,int-clock-stable-broken: when present, the controller always reports that the internal clock is stable even when it is not. - xlnx,mio-bank: When specified, this will indicate the MIO bank number in which the command and data lines are configured. If not specified, driver will assume this as 0.
