   1 * Freescale Enhanced Secure Digital Host Controller (eSDHC)
   2
   3 The Enhanced Secure Digital Host Controller provides an interface
   4 for MMC, SD, and SDIO types of memory cards.
   5
   6 Required properties:
   7   - compatible : should be
   8     "fsl,<chip>-esdhc", "fsl,esdhc"
   9   - reg : should contain eSDHC registers location and length.
  10   - interrupts : should contain eSDHC interrupt.
  11   - interrupt-parent : interrupt source phandle.
  12   - clock-frequency : specifies eSDHC base clock frequency.
  13   - sdhci,wp-inverted : (optional) specifies that eSDHC controller
  14     reports inverted write-protect state;
  15   - sdhci,1-bit-only : (optional) specifies that a controller can
  16     only handle 1-bit data transfers.
  17   - sdhci,auto-cmd12: (optional) specifies that a controller can
  18     only handle auto CMD12.

  20 Example:
  21
  22 sdhci@2e000 {
  23         compatible = "fsl,mpc8378-esdhc", "fsl,esdhc";
  24         reg = <0x2e000 0x1000>;
  25         interrupts = <42 0x8>;
  26         interrupt-parent = <&ipic>;
  27         /* Filled in by U-Boot */
  28         clock-frequency = <0>;
  29 };
