[PATCH v2 7/8] arm64: dts: qcom: x1e80100-qcp: mark l12b and l15b always-on
From: Johan Hovold
Date: Fri Mar 14 2025 - 10:56:55 EST
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")
