Subject: [PATCH v9 00/15] Clean up "mediatek,larb"
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.
[1] https://lore.kernel.org/linux-mediatek/20210702102304.3346429-1-hsinyi@chromium.org/
[2] https://lore.kernel.org/linux-mediatek/e7269c80-5437-6ab9-c1db-df0b94eb97d8@gmail.com/
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.
https://lore.kernel.org/linux-mediatek/20210709022324.1607884-1-eizan@chromium.org/
3) Add Frank's Tested-by. Remove Dafna's Tested-by as he requested.
v7: https://lore.kernel.org/linux-mediatek/20210730025238.22456-1-yong.wu@mediatek.com/
1) Fix a arm32 boot fail issue. reported from Frank.
2) Add a return fail in the mtk drm. suggested by Dafna.
v6: https://lore.kernel.org/linux-mediatek/20210714025626.5528-1-yong.wu@mediatek.com/
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.
