    directories.

-* 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.
-  - 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>;
-};
