Subject: Re: [PATCH v1 1/6] clk: divider: Implement and wire up .determine_rate by default

Quoting Martin Blumenstingl (2021-07-02 15:51:40)
> .determine_rate is meant to replace .round_rate. The former comes with a
> benefit which is especially relevant on 32-bit systems: since
> .determine_rate uses an "unsigned long" (compared to a "signed long"
> which is used by .round_rate) the maximum value on 32-bit systems
> increases from 2^31 (or approx. 2.14GHz) to 2^32 (or approx. 4.29GHz).
> 
> Implement .determine_rate in addition to .round_rate so drivers that are
> using clk_divider_{ro_,}ops can benefit from this by default. Keep the
> .round_rate callback for now since some drivers rely on
> clk_divider_ops.round_rate being implemented.
