Re: OPPv2 backporting on LSK 3.18/4.1

Thanks a lot Viresh!

It is a very interesting share. :)

The original 5250 have no so many level freq changes. Do you mean with your new settings in DT+OPPv2, the exynos 5250 can be set on any of appointed freq? like 1.7GHz/1.6GHz etc.?

Could you like to share how to control the system load to make the different freq setting and how to get the current cpu freq info?

I have not 5250 board to do the testing, but I have panda board and a mt8173 board, also a arndale octa. do you know if they work for OPPv2?

Thanks a lot for sharing! Alex
