Subject: [PATCH v6 2/2] riscv: dts: sophgo: cv180x: Allow the DMA multiplexer to set channel number for DMA controller
Date: Mon, 11 May 2026 14:38:17 +0800	[thread overview]
Message-ID: <20260511063818.463877-3-inochiama@gmail.com> (raw)
In-Reply-To: <20260511063818.463877-1-inochiama@gmail.com>

Change the DMA controller compatible to the sophgo,cv1800b-axi-dma,
which supports setting DMA channel number in DMA phandle args.

This dts change does not break backward compatibility as a fallback
compatiable string is added.

Fixes: 514951a81a5e ("riscv: dts: sophgo: cv18xx: add DMA controller")
Reported-by: Anton D. Stavinskii <stavinsky@gmail.com>
Closes: https://github.com/sophgo/linux/issues/9
