[RFC] device-tree: resets properties, reset topology, and shared resets

[Geert Uytterhoeven]

	Hi Rob, Mark,

Best Wishes for 2019!

Can you please provide your opinion on parsing the whole device tree for
"resets" phandle properties to find shared resets, cfr. patch [1] below?

This is a prerequisite for safe generic reset handling for
virtualization on DT-based platforms, cfr. patch [2].

Many thanks in advance!
