From 5dcf7898f6144266c814306003c1e0a5ee067011 Mon Sep 17 00:00:00 2001 From: David Brownell Date: Thu, 28 Jan 2010 13:58:20 -0800 Subject: [PATCH] ARM: reference DPM defn from v6/v7 arch spec The term "DPM" is probably not well known ("Device Power Management"?), so identify its source in the current ARM architecture specification. It's relevant to ARMv6, ARMv7-A, and ARMv7-R ... but not "M" profiles.
