From: Yong Wu <[email protected]>To simplify the code, Remove the power status checking in the tlb_flush_all, remove this: if (pm_runtime_get_if_in_use(data->dev) <= 0) continue; The mtk_iommu_tlb_flush_all is called from a) isr b) tlb flush range fail case c) iommu_create_device_direct_mappings In first two cases, the power and clock are always enabled. In the third case tlb flush is unnecessary because in a later patch in the series a full flush from the pm_runtime_resume callback is added. In addition, writing the tlb control register when the iommu is not resumed is ok and the write is ignored.
