Subject: [PATCH 04/18] power: ab8500_fg: Replace msleep() with usleep_range() for greater accuracy
Date: Tue, 15 Jan 2013 14:09:13 +0000 [thread overview]
Message-ID: <20130115140913.GC9379@gmail.com> (raw)
In-Reply-To: <1357909986-9262-5-git-send-email-lee.jones@linaro.org>
From: Jonas Aaberg <jonas.aberg@stericsson.com>
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.
