Subject: [PATCH v5 0/9] Renesas Capture Engine Unit (CEU) V4L2 driver

Hello,
   (hopefully) last round for CEU driver.

Changelog is quite thin, I have updated CEU driver MODULE_LICENSE to match
SPDX identifier, added Rob's and Laurent's Reviewed-by tags to bindings, and
made variables of "struct ceu_data" type static in the driver.

All of the patches are now Reviewed/Acked. Time to have this series included?

Thanks
   j

v4->v5:
- Added Rob's and Laurent's Reviewed-by tag to DT bindings
- Change CEU driver module license to "GPL v2" to match SPDX identifier as
  suggested by Philippe Ombredanne
- Make struct ceu_data static as suggested by Laurent and add his
  Reviewed-by to CEU driver.

v3->v4:
- Drop generic fallback compatible string "renesas,ceu"
- Addressed Laurent's comments on [3/9]
  - Fix error messages on irq get/request
  - Do not leak ceudev if irq_get fails
  - Make irq_mask a const field

v2->v3:
- Improved DT bindings removing standard properties (pinctrl- ones and
  remote-endpoint) not specific to this driver and improved description of
  compatible strings
- Remove ov772x's xlkc_rate property and set clock rate in Migo-R board file
- Made 'xclk' clock private to ov772x driver in Migo-R board file
- Change 'rstb' GPIO active output level and changed ov772x and tw9910 drivers
  accordingly as suggested by Fabio
- Minor changes in CEU driver to address Laurent's comments
- Moved Migo-R setup patch to the end of the series to silence 0-day bot
- Renamed tw9910 clock to 'xti' as per video decoder manual
- Changed all SPDX identifiers to GPL-2.0 from previous GPL-2.0+

v1->v2:
 - DT
 -- Addressed Geert's comments and added clocks for CEU to mstp6 clock source
 -- Specified supported generic video iterfaces properties in dt-bindings and
    simplified example

 - CEU driver
 -- Re-worked interrupt handler, interrupt management, reset(*) and capture
    start operation
 -- Re-worked querycap/enum_input/enum_frameintervals to fix some
    v4l2_compliance failures
 -- Removed soc_camera legacy operations g/s_mbus_format
 -- Update to new notifier implementation
 -- Fixed several comments from Hans, Laurent and Sakari

 - Migo-R
 -- Register clocks and gpios for sensor drivers in Migo-R setup
 -- Updated sensors (tw9910 and ov772x) drivers headers and drivers to close
    remarks from Hans and Laurent:
 --- Removed platform callbacks and handle clocks and gpios from sensor drivers
 --- Remove g/s_mbus_config operations
