Subject: [PATCH v2 06/10] arm64: dts: qcom: kitakami: Add Synaptics touchscreen
Date: Wed, 29 Jul 2020 14:00:52 +0200
Message-ID: <20200729120057.35079-7-konradybcio@gmail.com> (raw)
In-Reply-To: <20200729120057.35079-1-konradybcio@gmail.com>

All Kitakami devices seem to use the Synaptics RMI4
touchscreen attached to the same i2c bus. Configure and
enable it.
