This is unrelated. Perhaps make another patch to "correct" it.


I rolled it into this change series as I was asked in previous feedback
to make them 1 per line.

Do we need the soc phandle? If it isn't used we should leave it
out.


What about doing something like:

8992soc: soc {

This will allow it to be overriden.  Or would it be best to add it when
someone wants / needs to override it.

s/qcom,gcc/clock-controller/


done.


Also we typically just give it a "gcc" phandle to be terse.

is clock_gcc not a little more descriptive from a human perspective?

Sometimes being terse is hard for humans to parse.

qcom,gcc-msm8994


agreed.

clock-output-names can be removed because we use the same string
as the node name.


one less line works for me.
