This patch adds PPMU (Platform Performance Monitoring Unit) Device Tree node
for Exynos3250 based ARTIK5 module. The PPMU node is used to get the
utilization of DMC0/DMC1/LEFTBUS/RIGHTBUS Block.

What is the status with your devfreq patches? Instead of this one, there
should be just:
	#include "exynos4412-ppmu-common.dtsi"
(squashed into patch 5/10).

Best regards,
Krzysztof

I'm not working the devfreq patches(exynos-bus). Sorry for delay.
I'll again implement them by using DEVFREQ_NOTIFIER style according to (Myungjoo Ham's comment)

I drop the this patch on v2 patchset. After implementing the exynos-bus driver,
I'll send it.

Best Regards,
Chanwoo Choi
