Subject: [PATCH 3/4] omap3: pm: remove OPP interfaces from OMAP PM layer
Date: Tue, 10 Aug 2010 17:09:16 -0700 [thread overview]
Message-ID: <1281485357-20791-4-git-send-email-khilman@deeprootsystems.com> (raw)
In-Reply-To: <1281485357-20791-1-git-send-email-khilman@deeprootsystems.com>
With new OPP layer, OPP users will access OPP API directly instead of
using OMAP PM layer, so remove all notions of OPPs from the OMAP PM
layer.
