Subject: [PATCH v2 7/8] arm64: dts: qcom: x1e80100-qcp: mark l12b and l15b always-on
Date: Fri, 14 Mar 2025 15:54:39 +0100 [thread overview]
Message-ID: <20250314145440.11371-8-johan+linaro@kernel.org> (raw)
In-Reply-To: <20250314145440.11371-1-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: af16b00578a7 ("arm64: dts: qcom: Add base X1E80100 dtsi and the QCP dts")
