| * Cadence SD/SDIO/eMMC Host Controller |
| |
| 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 |
| Capabilities Register. Instead, the following properties should be specified |
| if supported. See mmc.txt for details. |
| - 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; |
| }; |
