The pll controller register set includes sets of registers with
different purposes, so it's logically to add syscon entry to be able
to access them from appropriate places.

Ignore this. It'll be included in "Introduce keystone reset driver" 
patch series

   I think it's better to follow the pattern established by "reset-controller" 
and use hyphen ISO dash in the node name. This is also a common practice to 
use hyphens in the device trees overall.

    Oops, hyphen and dash are basically the same thing; I meant 
s/dash/underscore/.

You meant s/underscore/dash.
I'll replace.
FYI: the change is included in new series [Patch v5 0/7] Introduce 
keystone reset driver

And this patch is squashed in:
[Patch v5 6/7] ARM: dts: keystone: update reset node to work with reset 
driver

Thanks.
