Subject: [PATCH 3/5] arm64: dts: qcom: msm8916-samsung-a5u: Add touch key regulator
Date: Fri, 4 Jun 2021 19:27:40 +0200 [thread overview]
Message-ID: <20210604172742.10593-3-stephan@gerhold.net> (raw)
In-Reply-To: <20210604172742.10593-1-stephan@gerhold.net>
On the Samsung Galaxy A5 the touch key is supplied by a single fixed
regulator (enabled via GPIO 97) that supplies both MCU and LED.
Add it to the device tree.
