Hello,
This patch series finally implements proper runtime PM support in Exynos
IOMMU driver. This has been achieved by using recently introduce device
links, which lets SYSMMU controller's runtime PM to follow master's device
runtime PM state (the device which actually performs DMA transaction).
Remove excessive, useless debug about skipping TLB invalidation, which
is a normal situation when more aggressive power management is enabled.

This patch uses recently introduced device links to track the runtime pm
state of the master's device. This way each SYSMMU controller is runtime
activated when its master's device is active and can save/restore its state
instead of being enabled all the time. This way SYSMMU controllers no
longer
