Subject: [PATCH 3/4] arm64: dts: qcom: sdm845: Add missing MDSS reset
Date: Tue, 17 Feb 2026 23:20:44 +0200 [thread overview]
Message-ID: <20260217-sdm845-hdk-v1-3-866f1965fef7@oss.qualcomm.com> (raw)
In-Reply-To: <20260217-sdm845-hdk-v1-0-866f1965fef7@oss.qualcomm.com>
From: David Heidelberg <david@ixit.cz>
If the OS does not support recovering the state left by the
bootloader it needs a way to reset display hardware, so that it can
start from a clean state. Add a reference to the relevant reset.
