Subject[PATCH v4 00/17] Clean up "mediatek,larb" after adding device_link
Date
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.

MediaTek IOMMU don't have its power-domain. 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.

This patchset depends on v5.7-rc1 and several patchset. Mainly venc and MDP
adjust their flow, then this patchset can work successfully.

a) IOMMU depend on [1][2].
b) MDP depend on [3][4][5].
c) VENC depend on [6].

[1][2][3] have already been in lastest linux-next.

Change notes:

v4: 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: http://lists.infradead.org/pipermail/linux-mediatek/2019-June/020440.html
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.

v1: https://lists.linuxfoundation.org/pipermail/iommu/2019-January/032387.html
