Subject: [PATCH 6/7] arm64: dts: allwinner: h616: Add DMA controller and DMA channels
From: Chen-Yu Tsai <wens@...e.org>
The DMA controllers found on the H616 and H618 are the same as the one
found on the H6. The only difference is the DMA endpoint (DRQ) layout.
Add a device node for it, and add DMA channels for existing peripherals.
