From 3c1bfc04c6292070ac4bd0a39976a3dbe6f00aa0 Mon Sep 17 00:00:00 2001 From: Jeffrey Ladouceur Date: Fri, 25 Jan 2013 10:38:53 +0000 Subject: [PATCH] powerpc/mpc85xx: Add revision properties in portal device tree node 'pme' The 'fsl,pme-rev1' and 'fsl-pme-rev2' properties have been added to the pme portal node. This is required for software to determine which version of PME hardware is present and take appropriate actions. These properties are a direct reflection of the corresponding ccsr pme register value. Also removed unnecessary static global variables.
