Subject: [PATCH v3 00/14] Clean up "mediatek,larb" after adding device_link
Date: Tue, 3 Sep 2019 17:37:22 +0800 [thread overview]
Message-ID: <1567503456-24725-1-git-send-email-yong.wu@mediatek.com> (raw)
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 "MT8183 IOMMU SUPPORT"[1].
[1] http://lists.infradead.org/pipermail/linux-mediatek/2019-August/022611.html
Change notes:
v3: 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.
