| * 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,<chip>-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. |
| |
| 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>; |
| }; |
