Subject: [PATCH v2 07/12] arm64: dts: qcom: msm8994: Add I2C, SPI and BLSP DMA nodes
Date:   Wed, 24 Jun 2020 00:48:06 +0200
Message-Id: <20200623224813.297077-8-konradybcio@gmail.com>
In-Reply-To: <20200623224813.297077-1-konradybcio@gmail.com>
References: <20200623224813.297077-1-konradybcio@gmail.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Add support for I2C and SPI buses to enable peripherals
such as touchscreens or sensors. Also add DMA nodes,
configuration and BLSP2 UART2 interface.
