    dma: imx-sdma: move to generic device tree bindings · 9479e17c
    Shawn Guo authored
    Update imx-sdma driver to adopt generic DMA device tree bindings.  It
    calls of_dma_controller_register() with imx-sdma specific of_dma_xlate
    to get the generic DMA device tree helper support.  The #dma-cells for
    imx-sdma must be 3, which includes request ID, peripheral type and
    priority.
    
    The existing way of requesting channel, clients directly call
    dma_request_channel(), still work there, and will be removed after
    all imx-sdma clients get converted to generic DMA device tree helper.
