Subject: [PATCH 7/7] arm64: dts: allwinner: sun50i-h616: Add SRAM nodes
Date: Wed, 25 Mar 2026 00:43:55 +0800	[thread overview]
Message-ID: <20260324164357.1607247-8-wens@kernel.org> (raw)
In-Reply-To: <20260324164357.1607247-1-wens@kernel.org>

From: Jernej Skrabec <jernej.skrabec@gmail.com>

The H616 SoC has a video engine, and two SRAM regions needed by it.

Add the SRAM regions to the dtsi file. The video engine will be added
in a separate change.
