Wysocki" , Grant Likely , Greg Kroah-Hartman Subject: [PATCH/RFC 3/6] OMAP1: runtime PM: drop platform bus implementation Date: Wed, 6 Apr 2011 17:02:46 -0700 Message-Id: <1302134569-22825-4-git-send-email-khilman@ti.com> X-Mailer: git-send-email 1.7.4 In-Reply-To: <1302134569-22825-1-git-send-email-khilman@ti.com> References: <1302134569-22825-1-git-send-email-khilman@ti.com> Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 3566 Lines: 139 Current runtime PM implementation on OMAP1 is is based on a deprecated interface: platform_bus_set_pm_ops(). Subsequent patch will convert OMAP1 runtime PM to an implementation shared with SH-mobile, and based on the new device power domain infrastructure in the common PM core.
