* Freescale Enhanced Secure Digital Host Controller (eSDHC) The Enhanced Secure Digital Host Controller provides an interface for MMC, SD, and SDIO types of memory cards. Required properties: - compatible : should be "fsl,-esdhc", "fsl,esdhc" - reg : should contain eSDHC registers location and length. - interrupts : should contain eSDHC interrupt. - interrupt-parent : interrupt source phandle. - clock-frequency : specifies eSDHC base clock frequency. - sdhci,wp-inverted : (optional) specifies that eSDHC controller reports inverted write-protect state; - sdhci,1-bit-only : (optional) specifies that a controller can only handle 1-bit data transfers. - sdhci,auto-cmd12: (optional) specifies that a controller can only handle auto CMD12. Example: sdhci@2e000 { compatible = "fsl,mpc8378-esdhc", "fsl,esdhc"; reg = <0x2e000 0x1000>; interrupts = <42 0x8>; interrupt-parent = <&ipic>; /* Filled in by U-Boot */ clock-frequency = <0>; };
