[PATCH v9 00/15] Clean up "mediatek,larb"

[Yong Wu <yong.wu@mediatek.com>]

MediaTek IOMMU block diagram always like below:

        M4U
         |
    smi-common
         |
  -------------
  |         |  ...
  |         |
larb1     larb2
  |         |
vdec       venc

All the consumer connect with smi-larb, then connect with smi-common.

When the consumer works, it should enable the smi-larb's power which also
need enable the smi-common's power firstly.

Thus, Firstly, use the device link connect the consumer and the
smi-larbs. then add device link between the smi-larb and smi-common.

After adding the device_link, then "mediatek,larb" property can be removed.
the iommu consumer don't need call the mtk_smi_larb_get/put to enable
the power and clock of smi-larb and smi-common.

Base on a jpeg dt-bing patchset[1] that already got the necessary R-b.

This patchset cross several tree, From [2], the media tree should be a good choice.

Change notes:
v9: 1) Add return -ENODEV when the dev is null.
    2) Add more strict about the case that a iommu consume device use the ports in
    different larbs. Don't allow this case.
    3) Remove two codec interface: mtk_vcodec_release_enc/dec_pm since it only has one
    line now.

v8: https://lore.kernel.org/linux-mediatek/20210929013719.25120-1-yong.wu@mediatek.com/
    1) Rebase on v5.15-rc1.
    2) Don't rebase the below mdp patchset that may still need more discuss.

    1) rebase on v5.14-rc1.
    2) Fix the issue commented in v5 from Dafna and Hsin-Yi.
    3) Remove the patches about using pm_runtime_resume_and_get since they have
       already been merged by other patches.

v5: https://lore.kernel.org/linux-mediatek/20210410091128.31823-1-yong.wu@mediatek.com/

    base on v5.7-rc1.
  1) Move drm PM patch before smi patchs.
  2) Change builtin_platform_driver to module_platform_driver since we may need
     build as module.
  3) Rebase many patchset as above.

v3: https://lore.kernel.org/linux-iommu/1567503456-24725-1-git-send-email-yong.wu@mediatek.com/

    2) Use device_is_bound to check whether the driver is ready from Matthias.    
    3) Add DL_FLAG_STATELESS flag when calling device_link_add and explain the
   reason in the commit message[3/14].
    4) Add a display patch[12/14] into this series. otherwise it may affect
   display HW fastlogo even though it don't happen in mt8183.
   
v2: https://lore.kernel.org/linux-iommu/1560171313-28299-1-git-send-email-yong.wu@mediatek.com/
   1) rebase on v5.2-rc1.
   2) Move adding device_link between the consumer and smi-larb into
iommu_add_device from Robin.
