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@xxxxxxxxxx> --- 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.
