Subject: [PATCH v2 09/11] arm64: dts: qcom: sdm845-samsung-starqltechn: Update panel compatible
Date: Thu, 24 Sep 2026 16:01:37 +0200	[thread overview]
Message-ID: <20260924-crosshatch-panel-v2-9-08d5c7bf72fc@ixit.cz> (raw)
In-Reply-To: <20260924-crosshatch-panel-v2-0-08d5c7bf72fc@ixit.cz>

From: David Heidelberg <david@ixit.cz>

Original compatible describing only the DDIC used, but omit describing
the panel used (Samsung AMB577PX01), which we have no way to detect.

New compatible allows without breaking ABI fixing the inverted reset.
