[PATCH v3 00/11] Add Amlogic C3 ISP pipeline handler and IPA

[Keke Li]

The Amlogic C3 platform integrates an ISP capable of supporting
multi-camera, multi-exposure high dynamic range (HDR) imaging with up to
14-bit raw RGB Bayer data.

The C3 ISP pipeline handler supports 3-channel image output,
1-channel 3A statistics ouput and 1-channel parameters input.

Link to the C3 ISP driver patch v6:
https://lore.kernel.org/linux-media/20250227-c3isp-v6-0-f72e19084d0d@amlogic.com/

Changes in v3:
- Separate commits for "Add C3 ISP pipeline handler"
- Separate commits for "Add C3 ISP IPA"
- Support Raw stream in the C3 ISP pipeline handler
- Rename some interfaces in c3-isp.mojom
- Use the camHelper's blacklevel in blc.cpp 

Changes in v2:
- Align struct c3_isp_params_xxx to 8 bytes in c3-isp-config.h
- Modify c3_isp_stats_buffer to c3_isp_stats_info in c3-isp-config.h
