Right, it's consumer side only which is the limitation I'm talking about
- at the minute it's only possible to use the clk API for on-SoC clocks
(or at least clocks that the SoC cares about), we don't have a clock API
for cross platform clock providers.  I don't know if getting a cross
platform implementation will change that situation much.
