From mboxrd@z Thu Jan 1 00:00:00 1970 From: Paul Walmsley Subject: [PATCH v2 01/12] OMAP2/3 clockdomains: add CM and PRM clkdms Date: Wed, 10 Sep 2008 10:47:36 -0600 Message-ID: <20080910164730.17024.2889.stgit@localhost.localdomain> References: <20080910164631.17024.43733.stgit@localhost.localdomain> Mime-Version: 1.0 Content-Type: text/plain; charset="utf-8" Content-Transfer-Encoding: 7bit Return-path: Received: from utopia.booyaka.com ([72.9.107.138]:58250 "EHLO utopia.booyaka.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1753388AbYIJQsv (ORCPT ); Wed, 10 Sep 2008 12:48:51 -0400 In-Reply-To: <20080910164631.17024.43733.stgit@localhost.localdomain> Sender: linux-omap-owner@vger.kernel.org List-Id: linux-omap@vger.kernel.org To: linux-omap@vger.kernel.org Cc: Paul Walmsley Add clockdomains for the CM and PRM. These will ultimately replace the "wkup_clkdm", which appears to not actually exist on the hardware.
