Note: This patch series remove the property mediatek,larb in the device tree. Therefore, the consumer (e.g. MDP, VDEC, VENC) drivers and deivce tree should be revised. Consumer drivers doesn't need to call mtk_smi_larb_get/put. Take care when migrating MT8365 and MT8385 drivers to K5.15.

memory: mtk-smi: Rename smi_gen to smi_type for MT8365
soc: mediatek: change the mutex defines and the mutex_mod type for MT8365

Test Pass:

  • Environment : i1200-demo + Linux mtk-v5.15-dev + This MR + MTK Proprietary test tool
  • Testcase : Allocate dma-buf through system heap and mtk proprietary heap, 1000 times memory write (size:0x101000) through following path:
  1. (vdosys0) Larb0 -> IOMMU_VDO -> MEMORY
  2. (vdosys0) Larb1 -> IOMMU_VPP -> MEMORY
  3. (vdosys1) Larb2 -> IOMMU_VDO -> MEMORY
  4. (vdosys1) Larb3 -> IOMMU_VPP -> MEMORY
  5. (vppsys0) Larb4 -> IOMMU_VPP -> MEMORY
  6. (vppsys1) Larb5 -> IOMMU_VDO -> MEMORY
  7. (vppsys1) Larb6 -> IOMMU_VPP -> MEMORY
  • Result : Buffer can be set to all 1 and all 0 without any iommu fault.
