Subject: [PATCH v6 00/11] Clean up "mediatek,larb"
Date:   Wed, 14 Jul 2021 10:56:15 +0800

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.

About the MM dt-binding/dtsi patches, I guess they should go together, thus
I don't split them for each a MM module and each a SoC.

Base on v5.14-rc1, and a jpeg[1] and mdp[2] patchset.

[2] https://lore.kernel.org/linux-mediatek/20210709022324.1607884-1-eizan@chromium.org/

Change notes:
v6: 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/
    1) Base v5.12-rc2.
    2) Remove changing the mtk-iommu to module_platform_driver patch, It have already been a
    independent patch.

v4: https://lore.kernel.org/linux-mediatek/1590826218-23653-1-git-send-email-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/
    1) rebase on v5.3-rc1 and the latest mt8183 patchset.
    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.
   3) add DL_FLAG_AUTOREMOVE_CONSUMER even though the smi is built-in from Evan.
   4) Remove the shutdown callback in iommu.
