iopoll: Tweak min sleep time used with usleep_range() Users of the iopoll macros may need to poll addresses that take a long time to update. In such cases, the hardcoded value of 1 us passed as the minimum delay to usleep_range() may result in reads that occur more often than necessary. Use (sleep_us/4) as the min delay instead of 1 us to resolve this is a scalable way. Change-Id: I8f679a7ecdb9ea2666c78aabca3c8ba806e0ead3 Signed-off-by: Matt Wagantall <mattw@codeaurora.org>
