Subject: [PATCH v4 0/4]  Add support for MAX96714F and MAX96717F GMSL2 ser/des

Change since v3:
- bindings
  - Renamed bindings to drop the 'f' suffix
  - Add bus type to MAX96717 and remove from MAX9674
  - Add lane-polarities to both bindings

- drivers
  - Address changes requested by Sakari in v3
  - use v4l2_subdev_s_stream_helper for MAX96714
  - do not init regmap twice in the MAX96714 driver
  - Fix compilations on 32 bits platforms

Each patch contains an exhaustive changelog compared to v3.

Krzysztof, I dropped your 'Reviewed-by' since there are some changes
in the binding patches.

Change since v2:
- Convert drivers to use CCI helpers
- Use generic node name
- Use 'powerdown' as gpio name instead of 'enable'
- Add pattern generator support for MAX96714

These patches add support for Maxim MAX96714F deserializer and
MAX96717F serializer.

MAX96714F has one GMSL2 input port and one CSI2 4 lanes output port,
MAX96717F has one CSI2 input port and one GMSL2 output port.

The drivers support the tunnel mode where all the
CSI2 traffic coming from an imager is replicated through the deserializer
output port.

Both MAX96714F and MAX96717F are limited to a 3Gbps forward link rate
leaving a maximum of 2.6Gbps for the video payload.
