From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>
Here's my second installment of SKL+ cdclk stuff. I've picked up Clint's latest
SKL/KBL cdclk patch and expanded on it quite a bit. After this series we're
capable of actually changing the DPLL0 VCO frequency dynamically, and a lot of
the code gets a much more uniform feel to it between SKL/KBL vs. BXT. This
should make it possible to land some future hardware work on top as well,
without making the code an awful mess.
Series available here:
