Subject: [PATCH 3/4] arm64: dts: qcom: msm8916-samsung-a2015: Add touchscreen regulator
Date: Sun, 26 Apr 2020 16:06:41 +0200 [thread overview]
Message-ID: <20200426140642.204395-4-stephan@gerhold.net> (raw)
In-Reply-To: <20200426140642.204395-1-stephan@gerhold.net>
A3U and A5U both use an extra touchscreen LDO regulator
that provides 3.3V for the touch screen controller.
Add it as fixed regulator to the common include.
