Change since v27:
- Rebase on v6.0-rc2
- Delete duplicate config in MDP3 Kconfig
- Relist maintainers in newly added bindings
- Minor changes in mtk-mdp3-comp.c and mtk-mdp3-reg.c to
avoid unnecessary long line warnings.
- The v4l2-compliance test results are the same as v26.

Change since v26:
- Set MMSYS config from "depend on" to "select" in MDP3 Kconfig
to avoid compilation errors of various combinations.
- Fix cast to smaller integer type 'enum mdp_comp_type' from
'const void *' in mtk_mdp3_comp.c.
- Fix sparse warnings in mtk_mdp3_comp.c.
- The v4l2-compliance test results are the same as v26.

Change since v25:
- Add more COMPILE_TEST config in MDP3 Kconfig
- Adjust unnecessary log level in "mdp_m2m_s_selection" function to
avoid spamming the kernel log for userspace errors.
- The v4l2-compliance test results list is as follows:

v4l2-compliance 1.23.0-4942, 32 bits, 32-bit time_t
v4l2-compliance SHA: 4cf258c24026 2022-07-28 15:43:45

Changes since v1:
- modify code for CMDQ v3 API support
- EC ipi cmd migration
- fix compliance test fail item (m2m cmd with -f) due to there is two problem in
runing all format(-f) cmd:
1. out of memory before test complete
Due to capture buffer mmap (refcount + 1) after reqbuf but seems
no corresponding munmap called before device close.
There are total 12XX items(formats) in format test and each format
alloc 8 capture/output buffers.
2. unceasingly captureBufs() (randomly)
Seems the break statement didn't catch the count == 0 situation:
In v4l2-test-buffers.cpp, function: captureBufs()
...
count--;
if (!node->is_m2m && !count)
break;
Log is as attachment

Hi,

This patch is used to present Media Data Path 3 (MDP3)
which provided scaling and color format conversion.
support using GCE to write register in critical time limitation.
support V4L2 m2m device control.
