Subject: [PATCH] arm64: dts: marvell: change regulator-gpio to regulator-fixed
Date: Mon, 5 Jan 2026 13:46:52 -0600 [thread overview]
Message-ID: <20260105194653.3189515-1-robh@kernel.org> (raw)
A "regulator-gpio" must have a GPIO control, hence the name. There's no
GPIO on a couple of Marvell platforms at least as far as the DT is
defined, so change the regulator type from GPIO to fixed.
Signed-off-by: Rob Herring (Arm) <robh@kernel.org>
