Subject: [PATCH v2 6/7] arm64: dts: allwinner: h616: Add DMA controller and DMA channels
Date: Sun, 28 Jan 2024 00:32:46 +0800
Message-Id: <20240127163247.384439-7-wens@kernel.org>
In-Reply-To: <20240127163247.384439-1-wens@kernel.org>
References: <20240127163247.384439-1-wens@kernel.org>

From: Chen-Yu Tsai <wens@csie.org>

The DMA controllers found on the H616 and H618 are the same as the one
found on the A100. The only difference is the DMA endpoint (DRQ) layout.

Add a device node for it, and add DMA channels for existing peripherals.

Signed-off-by: Chen-Yu Tsai <wens@csie.org>

Changes since v1:
- Fall back to A100 instead of H6
- Add DMA channels for r_i2c
