+* 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>;
+};
