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