-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>;
-};
