Subject: [PATCH v2 5/5] arm64: dts: qcom: sdm845-xiaomi-beryllium-tianma: Disable MDSS
Date: Tue, 17 Mar 2026 23:12:35 +0100 [thread overview]
Message-ID: <20260317-beryllium-fb-v2-5-36b69dfb760c@ixit.cz> (raw)
In-Reply-To: <20260317-beryllium-fb-v2-0-36b69dfb760c@ixit.cz>
From: Petr Hodina <petr.hodina@protonmail.com>
Currently the panel driver for tianma is broken.
Disable MDSS to prevent DRM taking over the framebuffer.
