[PATCH v4 12/13] iommu/rockchip: Add runtime PM support

2018-01-18 Thread Jeffy Chen
When the power domain is powered off, the IOMMU cannot be accessed and register programming must be deferred until the power domain becomes enabled. Add runtime PM support, and use runtime PM device link from IOMMU to master to startup and shutdown IOMMU. Signed-off-by: Jeffy Chen
