Based on linux-next tag: next-20250630

This patch set adds the MediaTek ISP7.x camera system hardware driver.

The driver sets up ISP hardware, handles interrupts, and initializes
V4L2 device nodes and functions. It also implements a V4L2 standard video
driver utilizing the media framework APIs, connects sensors and the ISP
via the seninf interface, and communicates with the SCP co-processor to
compose ISP registers in firmware.

These patches include:

CSI data reception from sensors Sensor interface bridge RAW/YUV image
pre-processing ISP utility and control modules

Changelog (v2):

 - Fix documentation typos 
 - Address review comments from v1

Note: At this stage (v2), the related firmware interface and headers are
still under development and review. Once the code is more stable and ready
for upstream submission, we will provide the corresponding linux-firmware
submission and clearly document which MediaTek SCP firmware version is
required for this driver.  Thank you for reviewing these patches.

Now I found v1. How did you address comment about compliance report?
