Subject: [PATCH v3 1/3] arm64: dts: rockchip: disable display subsystem for Radxa E52C
Date: Mon, 1 Sep 2025 18:00:25 +0800 [thread overview]
Message-ID: <20250901100027.164594-2-amadeus@jmu.edu.cn> (raw)
In-Reply-To: <20250901100027.164594-1-amadeus@jmu.edu.cn>
The Radxa E52C SBC do not have HDMI output, so disable
the display subsystem to avoid the following error log:
*ERROR* No available vop found for display-subsystem.
