Re: [PATCH 04/18] power: ab8500_fg: Replace msleep() withusleep_range() for greater accuracy

From: Lee Jones
Date: Tue Jan 15 2013 - 09:09:05 EST


From: Jonas Aaberg <jonas.aberg@xxxxxxxxxxxxxx>

Doing so provides a greater degree of accuracy when dealing with
time-frames between 1us and 20ms. msleep() is only accurate for
wake-ups greater than 20ms.
