Re: [PATCH v7 0/2] clk: intel: Add a new driver for a new clock controller IP

Hi Stephen Boyd,

After few rounds of review comments/updates from you & other reviewers,
this patch series seems to be lost :-\. No further review concerns or
acks from past 2 months.

I am wondering if this is due to any outstanding concerns/expectations
or it is just bad luck. Since you are the clk maintainer, may i ask you
to clarify what is it that i am missing. Thanks.

Regards,
Rahul
