From 317aa408d69a5b833a116317c18c7e957989ce44 Mon Sep 17 00:00:00 2001 From: Anders Larsen Date: Thu, 4 Mar 2010 11:22:53 +0100 Subject: ARM: 5975/1: AT91 slow-clock suspend: don't wait when turning PLLs off From: Julien Langer AT91: when turning off the PLLs during suspend, don't wait for the lock flag to be set. Previously the code would always run into the loop limitation of 1000 iterations because the flag is never set when turning the PLLs off.
