Subject: [PATCH 0/5] media: add FSD MIPI-CSI2 Rx controller driver

This patch series adds the V4L2 media driver for
Tesla Full Self Driving (FSD) SoC MIPI-CSI2 Rx controller.

The controller is compliant to MIPI CSI2 v1.3 specification.
It receives images from camera sensors over the D-PHY interface.

The D-PHY interface is compliant to MIPI D-PHY v1.2 specification. It
supports up to maximum of 4 data lanes.

V4L2 user control is provided to set the desired number of data lanes.

Maximum of up to 4 streams can be received simultaneously by one Rx
port. (Each streams identified by designated Virtual Channel
Identifier).

The controller instances consist of port property describing the endpoints.
When combined with remote-endpoint property the driver instantiates
video device nodes using V4L2 async subdev methods.

Streaming formats supported:
- YUV420
- RGB565, RGB666, RGB888
- RAW8, RAW10, RAW12
- JPEG

The driver implementation is verified on FSD evaluation board.

Thanks, Sathyakam
