[PATCH v6 2/2] arm64: dts: cix: add sky1 DMA-350 node with channel IRQ entries

From: Jun Guo <hidden>
Date: 2026-03-25 11:22:05
Also in: dmaengine, linux-devicetree, lkml
Subsystem: arm/cix soc support, the rest · Maintainers: Peter Chen, Fugang Duan, Linus Torvalds

Describe the DMA-350 channel interrupt sources in DT using 8
interrupt entries, while all entries map to the same GIC SPI
as wired on this platform.
