Subject: [PATCH 2/8] arm64: dts: qcom: x1e78100-t14s: mark l12b and l15b always-on
Date: Thu, 27 Feb 2025 09:13:51 +0100 [thread overview]
Message-ID: <20250227081357.25971-3-johan+linaro@kernel.org> (raw)
In-Reply-To: <20250227081357.25971-1-johan+linaro@kernel.org>
The l12b and l15b supplies are used by components that are not (fully)
described (and some never will be) and must never be disabled.
Mark the regulators as always-on to prevent them from being disabled,
for example, when consumers probe defer or suspend.
Fixes: 7d1cbe2f4985 ("arm64: dts: qcom: Add X1E78100 ThinkPad T14s Gen 6")
