From 5011466bade64483bb52bc4a926719d6794e6dab Mon Sep 17 00:00:00 2001 From: Inochi Amaoto Date: Mon, 11 May 2026 14:38:17 +0800 Subject: [PATCH] riscv: dts: sophgo: cv180x: Allow the DMA multiplexer to set channel number for DMA controller 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.
