Subject: [PATCH v7 2/2] arm64: dts: cix: add sky1 DMA-350 node with channel IRQ entries

From: Jun Guo <[email-masked]>
Date: Thu, 21 May 2026 15:29:24 +0800

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.
