Subject: [PATCH 5/5] riscv: dts: sifive: fu740: add PDMA device node
Date: Sat, 21 Feb 2026 03:43:57 +0800 [thread overview]
Message-ID: <20260221-pdma-v1-5-838d929c2326@sifive.com> (raw)
In-Reply-To: <20260221-pdma-v1-0-838d929c2326@sifive.com>
The FU740 SoC includes a 4-channel Platform DMA (PDMA) controller.
Add the device node to enable DMA support.
