Dear Maintainers,

I am pleased to submit this patch series that introduces the MediaTek
ISP7 Image System driver. This series consists of ten patches that
collectively add support for various components and functionalities of
the ISP7 architecture. The patches include device tree bindings, user
API definitions, V4L2 flow support, LARB device integration, CMDQ
support, SCP support, and image processing flows.

MediaTek's Image System (ImgSys), also known as ISP Pass2, is a
memory-to-memory hardware device designed for advanced image processing
tasks. ImgSys includes multiple hardware components such as TRAW, DIP,
PQDIP, ME, and WPE.

- **TRAW (Tile RAW)**:
  Provides multiple downscaled resizers for multi-scale noise reduction
  and supports RAW/RGB format conversion.

- **DIP (Digital Image Processing) and PQDIP (Picture Quality DIP)**:
  Supports temporal and spatial noise reduction (TNR/SNR), edge
  enhancement (EE), sharpness (SHP), image scaling, and rotation.

- **ME (Motion Estimation)**:
  Supports motion estimation between consecutive frames.

- **WPE (Warping Engine)**:
  Handles image warping and de-warping processes.

ImgSys utilizes Multi-Frame Combined Noise Reduction (MCNR) technology to
enhance image quality.

Below is a simplified architecture of the ImgSys driver:
User -> V4L2 Framework -> ImgSys Driver
     -> SCP (It packages the hardware settings into commands)
     -> ImgSys Driver
     -> CMDQ (The packaged commands are sent to the hardware via GCE)
     -> Hardware

Thease patches are base on linux-next/master, tag: next-20250523
Thank you for reviewing these patches.
