Re: [PATCH v5 0/9] clk: cs2000-cp: add dynamic mode and more features

Mike, Stephen,

Is there a chance to get this series reviewed and potentially queued for
5.16?

We have clearance for the devicetree side, and the functional changes of
the driver are all guarded by new feature flags, so my patches shouldn't
break existing setups.

Thanks a lot,
Daniel
