Subject: [PATCH v2 4/5] arm64: dts: rockchip: Add missing dp_out port for RK3399 CDN-DP
Date: Fri, 18 Jul 2025 14:26:18 +0800	[thread overview]
Message-ID: <20250718062619.99-5-kernel@airkyi.com> (raw)
In-Reply-To: <20250718062619.99-1-kernel@airkyi.com>

From: Chaoyi Chen <chaoyi.chen@rock-chips.com>

Let's make the ports nodes of cdn_dp in the same style as the other
display interface, and match the style of ports's yaml.
