Subject: [PATCH V4 4/6] ARM: dts: AM33XX: add clock nodes for CPU
Date: Fri, 12 Apr 2013 17:54:36 -0500	[thread overview]
Message-ID: <1365807278-554-5-git-send-email-nm@ti.com> (raw)
In-Reply-To: <1365807278-554-1-git-send-email-nm@ti.com>

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.

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.
