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].

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 Irui Wang (1): arm64: dts: mt8173: Separate mtk-vcodec-enc node Maoguang Meng (2): media: dt-binding: mtk-vcodec: Separating mtk-vcodec encode node. media: mtk-vcodec: separate mtk-vcodec-enc node.
