From 8c5ca4d29bf44eb4eb004683ca745742040c7486 Mon Sep 17 00:00:00 2001 From: Santosh Shilimkar Date: Fri, 11 Feb 2011 20:42:12 +0530 Subject: [PATCH] omap3: cpuidle: Add description field to each C-state. Add a description field to each idle C-state. This helps to give better data with PowerTop and one don't have to refer to the code to link what Cx means from system point of view while analysing PowerTop data. No functional change.
