* 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,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>;
};
