Subject: Re: [PATCH v2 3/4] clk: Move rate and accuracy recalc to mostly consumer APIs

Quoting Stephen Boyd (2020-02-05 15:28:01)
> There's some confusion about when recalc is done for the rate and
> accuracy clk consumer APIs in relation to the prepare lock being taken.
> Oddly enough, we take the lock again in debugfs APIs so that we can call
> the internal "clk_core" APIs to get these fields with any necessary
> recalculations. Instead of having this confusion, let's introduce a
> recalc variant of these two consumer APIs as internal helpers and call
> them from the consumer APIs and the debugfs code so that we don't take
> the lock more than once.
