From mboxrd@z Thu Jan 1 00:00:00 1970 From: Nishanth Menon Subject: [PATCH V4 4/6] ARM: dts: AM33XX: add clock nodes for CPU Date: Fri, 12 Apr 2013 17:54:36 -0500 Message-ID: <1365807278-554-5-git-send-email-nm@ti.com> References: <1365807278-554-1-git-send-email-nm@ti.com> Mime-Version: 1.0 Content-Type: text/plain Return-path: In-Reply-To: <1365807278-554-1-git-send-email-nm@ti.com> Sender: linux-kernel-owner@vger.kernel.org To: linux-omap@vger.kernel.org Cc: devicetree-discuss@lists.ozlabs.org, linux-kernel@vger.kernel.org, linux-arm-kernel@lists.infradead.org, =?UTF-8?q?Beno=C3=AEt=20Cousson?= , Tony Lindgren , Paul Walmsley , Kevin Hilman , Mike Turquette , Nishanth Menon List-Id: devicetree@vger.kernel.org AM33XX based platforms use dpll_mpu clock. Add same to common dtsi and remove the dummy clock node entry as AM33XX platform supports only device tree based boot. Cc: Benoit Cousson Cc: Kevin Hilman Cc: Paul Walmsley Cc: Tony Lindgren Signed-off-by: Nishanth Menon --- RFC of this patch was discussed in http://marc.info/?t=136370325600009&r=1&w=2 along with the detailed context as to why this is an intermediate step. previous revisions of cpufreq-cpu0 support do not use this approach.
