[PATCH v9 3/3] arm64: dts: imx8mq: add mipi csi phy and csi bridge descriptions

Martin Kepplinger
2021-07-26T08:21:51Z

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

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