[PATCH v3 0/5] of: Add helper for counting phandle refernces

[Grant Likely]

Well, this started as a single patch to get rid of horrible brute-force
counting of phandles and ended with fixes to the selftest code and
cleanups to the existing phandle parser before actually getting to the
new feature.

The selftest code is still a little fiddly to execute, but at least it
is consistent now. Sometime soon I'll link the selftest data directly
into the kernel so nothing special has to be done to run it, but I think
the DT grafting support needs to go in first.
