Subject: Re: [PATCH v2 00/12] clk: bcm281xx: updates for 3.15

Mike, I've given up on getting these in for 3.15, but
I want to be sure they're considered ASAP for 3.16.

You indicated you had questions about the prerequisite
clocks I proposed.  What I'd like to do is resend only the
first 7 patches of this series, leaving the patches that
implement prerequisite clock functionality to work out
separately.

In that case there is no special device tree dependency
that would require the patches be taken through arm-soc.

They do, however, still depend on the previous work that
was queued through arm-soc, so they don't apply on your
current clk-next branch.

How would you like me to handle this?

Thanks.
