since there has been no feedback for a while, a gentle reminder about this
patchset. 
Several patches have at least one Reviewed-by tag, with the exception of:

- PATCH 5, 8: those are, respectively, the driver for RP1 clock and misc core
  which have no major rework since the inception.

- PATCH 9, 10: those are new patches, where the most relevant change is a
  rearrangement of the dts include hierarchy to be flexible enough to support
  both the dtb overlay approach and the monolithic dtb.

- PATCH 13: just enables OF_OVERLAY config option. Some metric data have been
  added to help evaluating the impact.

Many thanks,

Andrea
