From abf89bc4bb09c16a53d693b09ea85225cf57ff39 Mon Sep 17 00:00:00 2001 From: Johan Hovold johan+linaro@kernel.org Date: Fri, 14 Mar 2025 15:54:33 +0100 Subject: [PATCH] arm64: dts: qcom: x1e80100-crd: mark l12b and l15b always-on

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.
