It was a really long time ago since this patch series was idle for a
while, but you previous had similar feedback in v3 but ended up OK
with it.  See:

https://patchwork.kernel.org/patch/10207583/

I believe the original node name came out of some back and forth
between Rob and Sean.  As far as I can tell, the context is back in
<https://patchwork.kernel.org/patch/10203483/>.  I think Rob wanted it
to follow other similar node names.


That all being said, if you feel strongly about it being called
"timing" and Rob's OK w/ that too then I'll re-spin the series.
