Sat Dec 5 00:53:04 PST 2015


Add operating-points-v2, clock, and regulator supply properties
required by mt8173-cpufreq driver to enable it.

Signed-off-by: Pi-Cheng Chen <pi-cheng.chen at linaro.org>

This patch is based on the patch[1] that adds underlying clock MUX for
MT8173 which is needed by mt8173-cpufreq driver but not yet picked.
