Subject: [PATCH v2 08/13] arm64: dts: qcom: msm8992: Add BLSP2_UART2 and I2C nodes
Date:   Thu, 25 Jun 2020 20:12:56 +0200
Message-Id: <20200625181303.129874-9-konradybcio@gmail.com>
In-Reply-To: <20200625181303.129874-1-konradybcio@gmail.com>
References: <20200625181303.129874-1-konradybcio@gmail.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Add support for I2C to enable support for peripherals
such as touchscreens or sensors. Also add BLSP_UART2 interface.

Please note that the naming scheme follows downstream and as
abominable as it is, that's what we get.
