Sorry to jump in late, but this only just caught my attention.

While I have no strong feelings on this series one way or the other, the
naming is a bit unfortunate. The clock device / clkdev naming is already
in use as an extension to the clock framework and is used by a wide
variety of embedded platforms already, with a pending patch to move it in
to the generic namespace (grepping for clkdev will give you an idea). The
idea behind that interface is similar in that it deals with the dynamic
creation and teardown of clocks, but is decoupled from timekeeping.

It's also reasonable to assume that devices with dynamic clocks tracked
through clkdev will wish to also use this interface in the timekeeping
case, so it would be good to settle on something less ambiguous in
advance.
