Right, in the initial RFC sent somehow only the replies were archived.
Although the RFC patch was a WIP patch in rough state, sent to take 
upstream inputs.
Will try adding the changelog in v2.
To give a context, in the RFC patch, we we're initially proposing a dt
based approach to set the actlr property, where we would piggyback on 
the iommus property to store actlr value and set the property during
smmu device probe.
