Subject: [PATCH v3 00/12] iommu/rockchip: Use OF_IOMMU


This series fixes some issues in rockchip iommu driver, and add of_iommu
support in it.

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().
