Required properties:
- compatible: should be one of the following:
“cdns,sd4hc” - default of the IP
“socionext,uniphier-sd4hc” - for Socionext UniPhier SoCs - reg: offset and length of the register set for the device.
- interrupts: a single interrupt specifier.
- clocks: phandle to the input clock.
Optional properties:
For eMMC configuration, supported speed modes are not indicated by the SDHCI

- mmc-ddr-1_8v
- mmc-ddr-1_2v
- mmc-hs200-1_8v
- mmc-hs200-1_2v
- mmc-hs400-1_8v
- mmc-hs400-1_2v
Example:
emmc: sdhci@5a000000 {
compatible = “socionext,uniphier-sd4hc”, “cdns,sd4hc”;
reg = <0x5a000000 0x400>;
interrupts = <0 78 4>;
clocks = <&clk 4>;
bus-width = <8>;
mmc-ddr-1_8v;
mmc-hs200-1_8v;
mmc-hs400-1_8v;
};
