Required properties:
-- compatible : Should be "fsl,<chip>-sdma"
+- compatible : Should be "fsl,imx31-sdma", "fsl,imx31-to1-sdma",
+ "fsl,imx31-to2-sdma", "fsl,imx35-sdma", "fsl,imx35-to1-sdma",
+ "fsl,imx35-to2-sdma", "fsl,imx51-sdma", "fsl,imx53-sdma" or
+ "fsl,imx6q-sdma". The -to variants should be preferred since they

+ the driver to work without additional firmware.
- reg : Should contain SDMA registers location and length
- interrupts : Should contain SDMA interrupt
- #dma-cells : Must be <3>.
