Hmm...so I'm not sure if some exynos5250 products use v3.4, it can use common struct clk for mass production?

If not, I think, this should be kept on v3.4 then it can be changed to use common struct clk from v3.5.

OK, sounds good to me.

If any branch is ready for it, please let me know.

Thanks for your sharing.

OK, I and my team will follow up 'common struct clk' for exynos5250 and it will be done maybe next week. And since I need to
implement other features for exynos5250 now, firstly let me use this and test this series in linux-next in a day.

Of course, if any updates, let you know.

Ah, one more, would be better to us if arm-soc tree could provide the topic branch for 'common struct clk' working as a base.

Thanks.

Best regards,
Kgene.
