Sorry for the late response.

AFAICT, all the providers that are used in imx6 and imx7 are using
(with this patchseries) the clk_hw_register (unless I'm missing something here).

Can you please be more specific and point out exactly which one isn't ?

I'll try to resend this before the end of next week.

As for the wrappers, they need to stay in until the last user of the clk
based API is switched to clk_hw based. That means all the remaining imx
platforms (1 through 5, and then 8). I chosed to do the imx6 and imx7
first because these are easier to find. Once this is in, I'll move on
with the imx8 and then the imx1 through imx5 (which are harder to find
nowadays).

Thanks for helping with the review on this.
