Changes in v5: Use out labels to save the duplication between the error and success paths. Use RK_MMU_POLL_PERIOD_US instead of 100. Remove clk names. Use clk_bulk APIs. Avoid race about pm_runtime_get_if_in_use() and pm_runtime_enabled(). Changes in v4: Rewrite commit message. Changes in v3: Also remove remove() and module_exit() as Tomasz suggested. Loop platform_get_irq() as Robin suggested. Add struct rk_iommudata. Squash iommu/rockchip: Use iommu_group_get_for_dev() for add_device Only call startup() and shutdown() when iommu attached. Remove pm_mutex. Check runtime PM disabled. Check pm_runtime in rk_iommu_irq(). Remove rk_iommudata->domain. Changes in v2: Move irq request to probe(in patch[0]) Move bus_set_iommu() to rk_iommu_probe().
