* Freescale Secure Digital Host Controller for i.MX2/3 series



This file documents differences to the properties defined in mmc.txt.



Required properties:

- compatible : Should be "fsl,<chip>-mmc", chip can be imx21 or imx31



Optional properties:

- dmas: One DMA phandle with arguments as defined by the devicetree bindings

	of the used DMA controller.

- dma-names: Has to be "rx-tx".



Example:



sdhci1: sdhci@10014000 {

	compatible = "fsl,imx27-mmc", "fsl,imx21-mmc";

	reg = <0x10014000 0x1000>;

	interrupts = <11>;

	dmas = <&dma 7>;

	dma-names = "rx-tx";

	bus-width = <4>;

	cd-gpios = <&gpio3 29>;

};
