Subject: [PATCH] MIPS: rb532: use mdelay to sleep when atomic

From: Phil Sutter <[email-masked]>
Date: Sat, 7 Feb 2009 15:57:26 +0100

In fact, using msleep() here triggers scheduling when the kernel has
been built with CONFIG_PREEMPT, which in turn causes the kernel to
complain about scheduling when being atomic.

The delay itself is basically a hack to allow the rb564 daughter board
(FIXME: right?) to be detected correctly. Maybe there is some real fix
for this issue, but sadly I can't test as I don't have any hardware
requiring this delay.
