Hi Elaine,

I really do expect a commit message explaining why the specific clocks
are needed to be critical.

The noc and arbiter clocks I somewhat understand, but I'll need
explanation on clocks like hclk_otg_pmu,  hclk_otg_pmu _etc_ [all these
non-noc / non-arbi clocks] on why there is no driver to handle them.

Also please group noc / arbi clocks together.


This applies to all patches in this series.

Thanks
Heiko
