From c6461f5c5970833cf28c5096cdfc7a095eb3bbb5 Mon Sep 17 00:00:00 2001 From: Paul Walmsley Date: Fri, 25 Feb 2011 15:49:53 -0700 Subject: OMAP2+: clock: disable autoidle on all clocks during clock init Disable autoidle on all clocks during clock framework initialization. (If CONFIG_PM is set, autoidle is re-enabled for all clocks later in the boot process.) The principle behind this patch, and some similar patches, is that the kernel should start with all power management features disabled. Later in the boot process, the PM code, if compiled in with CONFIG_PM, enables or re-enables power management features.
