    1 * NVIDIA Tegra APB DMA controller
    2 
    3 Required properties:
    4 - compatible: Should be "nvidia,<chip>-apbdma"
    5 - reg: Should contain DMA registers location and length. This shuld include
    6   all of the per-channel registers.
    7 - interrupts: Should contain all of the per-channel DMA interrupts.
    8 - clocks: Must contain one entry, for the module clock.
    9   See ../clocks/clock-bindings.txt for details.
   10 - resets : Must contain an entry for each entry in reset-names.
   11   See ../reset/reset.txt for details.
   12 - reset-names : Must include the following entries:
   13   - dma
   14 - #dma-cells : Must be <1>. This dictates the length of DMA specifiers in
   15   client nodes' dmas properties. The specifier represents the DMA request
   16   select value for the peripheral. For more details, consult the Tegra TRM's
   17   documentation of the APB DMA channel control register REQ_SEL field.
