Subject: [PATCH v2 00/12] Clean up "mediatek,larb" after adding device_link
Date: Mon, 10 Jun 2019 20:55:01 +0800 [thread overview]
Message-ID: <1560171313-28299-1-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].

Change notes:
v2:
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
