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. v1: https://lists.linuxfoundation.org/pipermail/iommu/2019-January/032387.html Yong Wu (13): 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: Get rid of mtk_smi_larb_get/put media: mtk-mdp: Get rid of mtk_smi_larb_get/put media: mtk-vcodec: Get rid of mtk_smi_larb_get/put drm/mediatek: Get rid of mtk_smi_larb_get/put memory: mtk-smi: Get rid of mtk_smi_larb_get/put iommu/mediatek: Use builtin_platform_driver memory: mtk-smi: Use device_is_bound to check if smi-common is ready 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 .../bindings/display/mediatek/mediatek,disp.txt | 9 ---- .../bindings/media/mediatek-jpeg-decoder.txt | 4 -- .../devicetree/bindings/media/mediatek-mdp.txt | 8 ---- .../devicetree/bindings/media/mediatek-vcodec.txt | 4 -- arch/arm/boot/dts/mt2701.dtsi | 1 - arch/arm/boot/dts/mt7623.dtsi | 1 - arch/arm64/boot/dts/mediatek/mt8173.dtsi | 15 ------ drivers/gpu/drm/mediatek/mtk_disp_ovl.c | 5 ++ drivers/gpu/drm/mediatek/mtk_disp_rdma.c | 5 ++ drivers/gpu/drm/mediatek/mtk_drm_crtc.c | 20 ++++---- drivers/gpu/drm/mediatek/mtk_drm_ddp_comp.c | 31 ++---------- drivers/gpu/drm/mediatek/mtk_drm_ddp_comp.h | 2 +- drivers/iommu/mtk_iommu.c | 56 ++++++++++------------ drivers/iommu/mtk_iommu_v1.c | 49 ++++++++++--------- drivers/media/platform/mtk-jpeg/mtk_jpeg_core.c | 22 --------- drivers/media/platform/mtk-jpeg/mtk_jpeg_core.h | 2 - drivers/media/platform/mtk-mdp/mtk_mdp_comp.c | 38 --------------- drivers/media/platform/mtk-mdp/mtk_mdp_comp.h | 2 - drivers/media/platform/mtk-mdp/mtk_mdp_core.c | 1 - .../media/platform/mtk-vcodec/mtk_vcodec_dec_pm.c | 22 --------- drivers/media/platform/mtk-vcodec/mtk_vcodec_drv.h | 3 -- drivers/media/platform/mtk-vcodec/mtk_vcodec_enc.c | 1 - .../media/platform/mtk-vcodec/mtk_vcodec_enc_pm.c | 47 ------------------ drivers/memory/mtk-smi.c | 41 +++++++--------- include/soc/mediatek/smi.h | 20 -------- 25 files changed, 93 insertions(+), 316 deletions(-) -- 1.9.1 _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
