Subject: [PATCH V5 6/6] ARM: OMAP3+: use cpu0-cpufreq driver in device tree supported boot
Date: Wed, 8 May 2013 14:06:16 -0500	[thread overview]
Message-ID: <1368039976-29648-7-git-send-email-nm@ti.com> (raw)
In-Reply-To: <1368039976-29648-1-git-send-email-nm@ti.com>

With OMAP3+ and AM33xx supported SoC having defined CPU device tree
entries with operating-points and clock nodes defined, we can now use
the SoC generic cpufreq-cpu0 driver by registering appropriate device.
