Subject: [PATCH 7/9] arm64: dts: qcom: kitakami: Add Synaptics touchscreen
Date: Tue, 28 Jul 2020 14:00:46 +0200 [thread overview]
Message-ID: <20200728120049.90632-8-konradybcio@gmail.com> (raw)
In-Reply-To: <20200728120049.90632-1-konradybcio@gmail.com>
All Kitakami devices seem to use the Synaptics RMI4
touchscreen attached to the same i2c bus. Configure and
enable it.
