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-bindings/dtsi patches, I guess they will go through Matthias's tree, so I don't split them for each a MM module and each a SoC. This patchset base on v5.12-rc2 and a vcodec patchset(separating its node)[1] which has already been in linux-next. [1] https://lore.kernel.org/linux-mediatek/20210325122625.15100-1-irui.wang@mediatek.com/ Change notes: v5: 1) Base on v5.12-rc2. 2) Remove changing the mtk-iommu to module_platform_driver patch, It have already been a independent patch. 3) Add several patches for the MM drivers with pm_runtime_resume_and_get instead of pm_runtime_get_sync since smi already use it. 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. v1: https://lore.kernel.org/linux-iommu/1546318276-18993-1-git-send-email-yong.wu@mediatek.com/ Yong Wu (15): dt-binding: mediatek: Get rid of mediatek,larb for multimedia HW iommu/mediatek: Add probe_defer for smi-larb iommu/mediatek: Add device_link between the consumer and the larb devices memory: mtk-smi: Add device-link between smi-larb and smi-common media: mtk-jpeg: Use pm_runtime_resume_and_get for PM get_sync media: mtk-jpeg: Get rid of mtk_smi_larb_get/put media: mtk-mdp: Use pm_runtime_resume_and_get for PM get_sync media: mtk-mdp: Get rid of mtk_smi_larb_get/put drm/mediatek: Use pm_runtime_resume_and_get for PM get_sync drm/mediatek: Get rid of mtk_smi_larb_get/put media: mtk-vcodec: Use pm_runtime_resume_and_get for PM get_sync media: mtk-vcodec: Get rid of mtk_smi_larb_get/put memory: mtk-smi: Get rid of mtk_smi_larb_get/put arm: dts: mediatek: Get rid of mediatek,larb for MM nodes arm64: dts: mediatek: Get rid of mediatek,larb for MM nodes Yongqiang Niu (1): drm/mediatek: Add pm runtime support for ovl and rdma .../display/mediatek/mediatek,disp.txt | 9 ---- .../bindings/media/mediatek-jpeg-decoder.txt | 4 -- .../bindings/media/mediatek-jpeg-encoder.txt | 4 -- .../bindings/media/mediatek-mdp.txt | 8 ---- .../bindings/media/mediatek-vcodec.txt | 4 -- arch/arm/boot/dts/mt2701.dtsi | 2 - arch/arm/boot/dts/mt7623n.dtsi | 5 -- arch/arm64/boot/dts/mediatek/mt8173.dtsi | 16 ------- arch/arm64/boot/dts/mediatek/mt8183.dtsi | 5 -- drivers/gpu/drm/mediatek/mtk_disp_ovl.c | 9 +++- drivers/gpu/drm/mediatek/mtk_disp_rdma.c | 9 +++- drivers/gpu/drm/mediatek/mtk_drm_crtc.c | 21 +++++---- drivers/gpu/drm/mediatek/mtk_drm_ddp_comp.c | 35 -------------- drivers/gpu/drm/mediatek/mtk_drm_ddp_comp.h | 1 - drivers/gpu/drm/mediatek/mtk_drm_drv.c | 5 +- drivers/iommu/mtk_iommu.c | 24 +++++++++- drivers/iommu/mtk_iommu_v1.c | 22 ++++++++- .../media/platform/mtk-jpeg/mtk_jpeg_core.c | 34 ++------------ .../media/platform/mtk-jpeg/mtk_jpeg_core.h | 2 - drivers/media/platform/mtk-mdp/mtk_mdp_comp.c | 40 ---------------- drivers/media/platform/mtk-mdp/mtk_mdp_comp.h | 2 - drivers/media/platform/mtk-mdp/mtk_mdp_core.c | 1 - drivers/media/platform/mtk-mdp/mtk_mdp_m2m.c | 4 +- .../platform/mtk-vcodec/mtk_vcodec_dec_pm.c | 42 ++++------------- .../platform/mtk-vcodec/mtk_vcodec_drv.h | 3 -- .../platform/mtk-vcodec/mtk_vcodec_enc.c | 1 - .../platform/mtk-vcodec/mtk_vcodec_enc_pm.c | 46 ++----------------- drivers/memory/mtk-smi.c | 33 ++++--------- include/soc/mediatek/smi.h | 20 -------- 29 files changed, 99 insertions(+), 312 deletions(-) -- 2.18.0 _______________________________________________ iommu mailing list iommu@lists.linux-foundation.org https://lists.linuxfoundation.org/mailman/listinfo/iommu
