1* Renesas USB DMA Controller Device Tree bindings
2
3Required Properties:
4- compatible: must contain "renesas,usb-dmac"
5- reg: base address and length of the registers block for the DMAC
6- interrupts: interrupt specifiers for the DMAC, one for each entry in
7  interrupt-names.
8- interrupt-names: one entry per channel, named "ch%u", where %u is the
9  channel number ranging from zero to the number of channels minus one.
10- clocks: a list of phandle + clock-specifier pairs.
11- #dma-cells: must be <1>, the cell specifies the channel number of the DMAC
12  port connected to the DMA client.
13- dma-channels: number of DMA channels
