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>;
|
|
status = "okay";
|
|
};
