Kernel-2.6.32-573.12.1.el6_esdhc

• 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.

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>;
};
