    serial: pl011: use generic DMA slave configuration if possible · 787b0c1f
    Arnd Bergmann authored
    With the new OF DMA binding, it is possible to completely avoid the
    need for platform_data for configuring a DMA channel. In cases where the
    platform has already been converted, calling dma_request_slave_channel
    should get all the necessary information from the device tree.
    
    This also adds a binding document specific to the pl011 controller,
    and extends the generic primecell binding to mention "dmas" and other
    common properties.
    
    Like the patch that converts the dw_dma controller, this is completely
    untested and is looking for someone to try it out.
