Subject: [PATCH] arm64: dts: qcom: qrb4210-rb2: make L9A always-on
Date: Mon, 03 Jun 2024 15:49:10 +0300 [thread overview]
Message-ID: <20240603-rb2-l9a-aon-v1-1-81c35a0de43d@linaro.org> (raw)
The L9A regulator is used to further control voltage regulators on the
board. Make sure that is stays always on to prevent undervolting some of
the volage rails.
Fixes: 8d58a8c0d930 ("arm64: dts: qcom: Add base qrb4210-rb2 board dts")
