Subject: [PATCH v1 3/3] arm64: dts: imx8mq: add mipi csi phy and csi bridge descriptions
Date:   Thu, 27 May 2021 09:54:07 +0200
Message-Id: <20210527075407.3180744-4-martin.kepplinger@puri.sm>
In-Reply-To: <20210527075407.3180744-1-martin.kepplinger@puri.sm>
References: <20210527075407.3180744-1-martin.kepplinger@puri.sm>

Precedence: bulk

Describe the 2 available CSI interfaces on the i.MX8MQ with the MIPI-CSI2
receiver and the CSI Bridge that provides the user buffers.

An image sensor is to be connected to the MIPIs' second port, described in
board files.
