Change since v15:
- Depend on:
  [1] https://patchwork.kernel.org/project/linux-mediatek/list/?series=640926
- Split the bindings under ./soc/mediatek into a separate patch.
- Fix data abort in "mdp_auto_release_work"
- Adjust the steps in the function "mdp_cmdq_send" to make the error handling
  more reasonable

Change since v14:
- Rebase on v5.18-rc6
- Depend on:
  [1] https://patchwork.kernel.org/project/linux-mediatek/list/?series=640926
- In response to CMDQ API change, replace the function "cmdq_pkt_flush_async"
  with the standard APIs of mbox
- Fix the description of "mediatek,gce-client-reg" property in MDP3-related

Change since v13:
- Rebase on v5.18-rc4
- Depend on:
  [1] https://patchwork.kernel.org/project/linux-mediatek/list/?series=636041
- Remove advanced functionality about ISP settings for direct link cases.
- Remove the software designation in the mt8183 dts and
  revise corresponding bindings.

Change since v12:
- Rebase on linux-next
- Depend on:
  [1] https://patchwork.kernel.org/project/linux-mediatek/list/?series=630948
- Remove messages related to routing information in MDP3, and leave the related
  settings in MMSYS.
- Remove unnecessary phandle and redundant property in RDMA dt-binding and
  adjust the corresponding driver.
- Revise MDP3 node name in dts. 
- Removed unnecessary functions, mutex and work queue in MDP3 driver
- Fixed format mapping error for V4L2_PIX_FMT_RGB565X

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
- 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
- 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

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()
                        if (!node->is_m2m && !count)
        Log is as attachment


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.
