[PATCH 00/18] Add DT support for CSI2RX multi-stream

[Yemike Abhilash Chandra]

Driver support for CSI2RX multi-stream was merged last cycle[0]. This
series adds the corresponding device tree support.

Patch 1 is a cleanup fixing indentation in the existing CSI2RX nodes.

The next few patches i.e. (Patch 2 to Patch 6) add the additional DMA
channels required for CSI2RX multi-stream capture.

Multi-stream capture uses a SERDES pair based on the FPD-Link or
V3Link protocol. The serializer takes the input from a camera sensor
and converts it to the FPD-Link standard, while the deserializer
aggregates streams from multiple serializers and sends them over the
CSI-2 RX interface. Each CSI2RX instance therefore indirectly receives
input from multiple sensors.

The remaining patches add overlays for various deserializer boards,
and for the UB953 serializer with the IMX219 sensor. Also enabling
DS90UB960 deserializer and DS90UB953 serializer drivers in the
arm64 defconfig.

(grep for "ds90ub960" for the deserializer logs and "ds90ub953" for the serializer.
 grep for "running tests" to see the actual test pattern genertaion capture logs from
 the sensor over the SERDES)
