From 6896ca5a9d05275fbeb38640c9bbdb95698de188 Mon Sep 17 00:00:00 2001 From: Chen-Yu Tsai Date: Tue, 24 Mar 2026 01:19:26 +0800 Subject: [PATCH] arm64: dts: allwinner: sun55i: Fix r-spi DMA r-spi has DRQs for both the main and MCU DMA controllers on the A523 SoC family, however it seems it that it is mainly routed to the MCU DMA controller, with no obvious way to change it. Change the DMA channels of r-spi to the MCU so that it works properly.
