From mboxrd@z Thu Jan 1 00:00:00 1970 From: Philipp Zabel Subject: [PATCH v6 7/8] ARM i.MX5: Add System Reset Controller (SRC) support for i.MX51 and i.MX53 Date: Thu, 28 Mar 2013 17:35:22 +0100 Message-ID: <1364488523-20310-8-git-send-email-p.zabel@pengutronix.de> References: <1364488523-20310-1-git-send-email-p.zabel@pengutronix.de> Return-path: In-Reply-To: <1364488523-20310-1-git-send-email-p.zabel@pengutronix.de> Sender: linux-pm-owner@vger.kernel.org To: linux-arm-kernel@lists.infradead.org, Arnd Bergmann Cc: Greg Kroah-Hartman , Stephen Warren , Marek Vasut , Fabio Estevam , Sascha Hauer , Shawn Guo , kernel@pengutronix.de, devicetree-discuss@lists.ozlabs.org, Mike Turquette , Len Brown , Pavel Machek , "Rafael J. Wysocki" , linux-pm@vger.kernel.org, Philipp Zabel List-Id: devicetree@vger.kernel.org The SRC in i.MX51 and i.MX53 is similar to the one in i.MX6q minus the IPU2 reset line and multi core CPU reset/enable bits.
