    ARM: OMAP: omap_device: Do not overwrite resources allocated by OF layer · b82b04e8
    Vaibhav Hiremath authored
    With the new devices (like, AM33XX and OMAP5) we now only support
    DT boot mode of operation and now it is the time to start killing
    slowly the dependency on hwmod, so with this patch, we are starting
    with device resources.
    The idea here is implemented considering to both boot modes -
      - DT boot mode
        OF framework will construct the resource structure (currently
        does for MEM & IRQ resource) and we should respect/use these
        resources, killing hwmod dependency.
        If pdev->num_resources > 0, we assume that MEM & IRQ resources
        have been allocated by OF layer already (through DTB).
    
        Once DMA resource is available from OF layer, we should
        kill filling any resources from hwmod.
    
      - Non-DT boot mode
        Here, pdev->num_resources = 0, and we should get all the
        resources from hwmod (following existing steps)
