* 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,mpc8379-esdhc" for MPC83xx processors.

    "fsl,<chip>-esdhc", "fsl,mpc8536-esdhc" for MPC85xx processors.

  - 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.



Example:



sdhci@2e000 {

	compatible = "fsl,mpc8378-esdhc", "fsl,mpc8379-esdhc";

	reg = <0x2e000 0x1000>;

	interrupts = <42 0x8>;

	interrupt-parent = <&ipic>;

	/* Filled in by U-Boot */

	clock-frequency = <0>;

};
