Subject: [PATCH v4 0/4] media: mediatek: support mdp3 on mt8183 platform

From: daoyuan huang <daoyuan.huang@...iatek.com>

Changes since v3:
- Rebase on v5.9-rc1.
- modify code for review comment from Rob Herring, cancel multiple nodes using
  same register base situation.
- control IOMMU port through pm runtime get/put to DMA components' device.
- SCP(VPU) driver revision.
- stop queuing jobs(remove flush_workqueue()) after mdp_m2m_release().
- add computation of plane address with data_offset.
- fix scale ratio check issue.
- add default v4l2_format setting.

Changes since v2:
- modify code for review comment from Tomasz Figa & Alexandre Courbot
- review comment from Rob Herring will offer code revision in v4, due to
  it's related to device node modification, will need to modify code
  architecture

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

I will paste the test result with problem part in another e-mail

Hi,

This is the first version of RFC patch for Media Data Path 3 (MDP3),
MDP3 is used for scaling and color format conversion.
support using GCE to write register in critical time limitation.
support V4L2 m2m device control.

daoyuan huang (4):
  [v4,1/4] dt-binding: mt8183: Add Mediatek MDP3 dt-bindings
  [v4,2/4] dts: arm64: mt8183: Add Mediatek MDP3 nodes
  [v4,3/4] media: platform: Add Mediatek MDP3 driver KConfig
  [v4,4/4] media: platform: mtk-mdp3: Add Mediatek MDP3 driver
