[PATCH 00/13] clk: add new flag CLK_ROUNDING_FW_MANAGED

[Brian Masney]

There are some clocks where the rounding is managed by the hardware, and
the determine_rate() clk ops is just a noop that simply returns 0. Based
on discussions with Stephen at Linux Plumbers Conference, he suggested
adding a flag for this particular case. So let's add a new flag, and
update the clk core so that the determine_rate() clk op is not required
when this flag is set.
    
This series adds the flag, some kunit tests, and updates all of the
relevant drivers under drivers/clk to use the new flag.
    
Once this is merged, and in Linus's tree, I can update the few remaining
clk drivers that are outside of drivers/clk via those subsystems at a
later time.

Merge Strategy
--------------
All of this needs to be directly merged by Stephen as one series into
his tree. Subsystem maintainers: please leave a Reviewed-by or Acked-by.
To reduce the noise, I am only CCing people on their respective drivers.

Note this series depends on 3 previously-posted patches in this git pull
to Stephen for v7.1.

Hopefully I set the depeendencies up correctly in b4.
