Subject[PATCH v19 0/4] media: mediatek: support mdp3 on mt8183 platform
Change since v18:
- Rebase on linux-next.
- Adjust copyright date of MDP3 driver.
- Functions renaming as follows:
[1] is_output_disable() => is_output_disabled()
[2] mdp_component_init() => mdp_comp_config()
[3] mdp_component_deinit() => mdp_comp_destroy()
[4] mdp_comp_ctx_init() => mdp_comp_ctx_config()
[5] mdp_sub_comps_create() => mdp_comp_sub_create()
- Document MDP3 10-bit format descriptions in "mtk-mdp3-regs.c".
- Add error control for functions mdp_comp_clocks_on and mdp_comp_clock_on.
- Moved function "mtk_mutex_put" from function
"mdp_comp_destroy"(renamed from mdp_component_deinit) to avoid semantic ambiguity.
- For some allocated parameters, assign a value of NULL after freeing
to avoid the possibility of repeated use.
- Removed unnecessary timestamp pass flow.
- About parameters passed by the user in function "mdp_try_fmt_mplane", add relevant checks to
clamp them in a reasonable range to avoid the possibility of overflow

Change since v17:
- Depend on:
- In response to future CMDQ api changes listed below:
adjust CMDQ flush and callback flow in MDP3.

Change since v16:
- Rebased on v5.19-rc1
- Depend on:
- In response to MUTEX changes, adjust API naming and parameters when
used in function "mdp_path_subfrm_require".
- Remove unnecessary MDP3 phandle in 8183 dts.

Change since v15:
- Depend on:
- 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:
- 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:
- 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:
- 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:
- 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.
