Subject: Re: [PATCH V2] clk: ux500: add range to usleep_range

Quoting Nicholas Mc Guire (2019-04-11 04:04:11)
> Providing a range for usleep_range() allows the hrtimer subsystem to
> coalesce timers - the delay is runtime configurable so a factor 2
> is taken to provide the range. With the expected range for
> enable_delay_us being milliseconds, the range should lie in the 250us
> range which is sufficient for hrtimer optimization.
