 * Freescale Smart Direct Memory Access (SDMA) Controller for i.MX
 
 Required properties:
-- 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
-  allow to determnine the correct ROM script addresses needed for
-  the driver to work without additional firmware.
+- compatible : Should be one of
+      "fsl,imx25-sdma"

 - reg : Should contain SDMA registers location and length
 - interrupts : Should contain SDMA interrupt
 - #dma-cells : Must be <3>.
