Subject: [PATCH 2/6] arm64: dts: qcom: sc8280xp-x13s: mark s10b regulator as always-on
Date: Wed, 22 Mar 2023 12:33:14 +0100 [thread overview]
Message-ID: <20230322113318.17908-3-johan+linaro@kernel.org> (raw)
In-Reply-To: <20230322113318.17908-1-johan+linaro@kernel.org>
The s10b supply is used by several components that are not (yet)
described in devicetree (e.g. ram, charger, ec) and must not be
disabled.
Mark the regulator as always-on.
Fixes: f29077d86652 ("arm64: dts: qcom: sc8280xp-x13s: Add soundcard support")
