Subject: [PATCH v1 2/2] arm64: dts: qcom: x1e80100-dell-xps13-9345: fix nvme regulator boot glitch
Date: Wed, 16 Oct 2024 22:15:49 +0200	[thread overview]
Message-ID: <20241016202253.9677-3-alex.vinarskis@gmail.com> (raw)
In-Reply-To: <20241016202253.9677-1-alex.vinarskis@gmail.com>

The NVMe regulator has been left enabled by the boot firmware. Mark it
as such to avoid disabling the regulator temporarily during boot.

Based on https://lore.kernel.org/all/20241016145112.24785-1-johan+linaro@kernel.org/

Fixes: f5b788d0e8cd ("arm64: dts: qcom: Add support for X1-based Dell XPS 13 9345")
