From c912f7e1eae169aaca333b4c5da3f36c98f2ccb0 Mon Sep 17 00:00:00 2001 From: Kevin Hilman Date: Fri, 15 May 2009 11:29:28 -0700 Subject: [PATCH] OMAP1: PM: update and decouple from OMAP2/3 PM core Update OMAP1-specific PM infrastructure. This is a sync of what is in linux-omap for OMAP1. This mostly de-couples OMAP1 PM from OMAP2/3 PM and renames things accordingly, and removes omap2/3 specific code from OMAP1 specific headers. Original OMAP1 decoupling patch for OMAP PM branch by Paul Walmsley.
