Subject: [PATCH 2/4] arm64: dts: imx8mm-tqma8mqml: remove virtual 1.8V regulator
Date: Tue, 16 Dec 2025 14:31:05 +0100	[thread overview]
Message-ID: <20251216133110.905950-2-alexander.stein@ew.tq-group.com> (raw)
In-Reply-To: <20251216133110.905950-1-alexander.stein@ew.tq-group.com>

From: Markus Niebel <Markus.Niebel@ew.tq-group.com>

BUCK5 regulator supplies the 1.8V rail. Use the actual regulator
instead of a virtual fixed regulator.
