Hi Mike, Stephen,
As the .round_rate() callback returns a long clock rate, it cannot
return clock rates that do not fit in signed long, but do fit in
unsigned long. The newer .determine_rate() callback does not suffer
from this limitation. In addition, .determine_rate() provides the
ability to specify a rate range.
Hence this patch series switches the Z (CPU) and SD clocks in the R-Car
Gen2 and Gen3 clock drivers from the .round_rate() to the
.determine_rate() callback.
Note that the "div6" clock driver hasn't been converted yet, so div6
clocks still use .round_rate().
This has been tested on R-Car M2-W and R-Car M3-N, and should have no
behavioral impact.
To be queued in clk-renesas-for-v5.3, if approved.
Thanks for your comments!
