Subject: [PATCH v12 0/3] media: mediatek: support mdp3 on mt8183 platform

Change since v11:
- Rebase on linux-next tag:next-20220316
- Depend on:
  [1] https://patchwork.kernel.org/project/linux-mediatek/list/?series=624281
- Remove redundant hardware index in data-binding suggested by Rob Herring.
- Referring to Rob Herring's suggestion to improve some descriptions in the RDMA dt-binding
- Move MDP3 file folder from "./drive/media/platform/mtk-mdp3" to "./driver/media/platform/mediatek/mdp3"
- Fixed the V4L2 and MDP color format mapping error in RGB565 which checked by Benjamin Gaignard

Change since v10:
- The routing table needs to be discarded, and the calculation result
  on the SCP side is used to write a suitable mux setting for
  1 input port and 2 output ports.
- Adjust dts parsing flow to remove redundant HW IDs.
- Fix memory leak caused by no free path information in function "mdp_cmdq_send".

Change since v9:
- Keep only the MDP3 driver patches and split the remaining mmsys and
  mutex patches into another mail.
- Move mutex mod settings to corresponding driver and make relevant adjustments
  for this in MDP3 driver.
- Fix compile warning reported by kernel test robot.

Change since v8:
- Rebase on v5.16-rc2.
- Refer to Angelo's suggestion, adjust the register writing format to increase
  readability and significance.
- Refer to Angelo's suggestion, adjust or reduce inappropriate debugging
  messages.
- Refer to Rob Herring's suggestion to correct the the binding file
  to make it with the specification.
- Fix compile warning reported by kernel test robot.

Change since v7:
- Rebase on v5.15-rc6.
- Revise several V4L2 M2M settings to pass v4l2-compliance test.
- Integrate those same component dt-binding documents of DRM and MDP, and
  move them under the MMSYS domain.
- Split MMSYS and MUTEX into two different files according to
  their functional properties.

Changes since v6:
- Refactor GCE event to corresponding node.
- Fix dt_binding_check fail.
- Fix compilation errors.

Changes since v5:
- Rebase on v5.14-rc6.
- Move MMSYS/Mutex settings to corresponding driver.
- Revise the software license description and copyright.
- Remove unnecessary enum. or definitions.
- Optimize platform/chip definition conditions.
- Use general printing functions instead of MDP3 private ones.
- Fix compile warning.

Changes since v4:
- Rebase on v5.13-rc1.
- Remove the CMDQ flush flow to match the CMDQ API change.
- Integrate four of MDP's direct-link subcomponents into MDP controller node
  from syscon node to avoid illegal clock usage.
- Rewrite dt-binding in a JSON compatible subset of YAML
- Fix a bit of macro argument precedence.

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.

Moudy Ho (3):
  dt-binding: mt8183: add Mediatek MDP3 dt-bindings
  dts: arm64: mt8183: add Mediatek MDP3 nodes
  media: platform: mtk-mdp3: add Mediatek MDP3 driver
