Repeating my comments from v6:
nit that you're adding an extra blank line here that you don't need.
Given the quantity of outstanding dts patches though, it's almost
certain that Andy will need to manually resolve conflicts when
applying this patch so presumably he can fix up when he lands.
In any case, feel free to add:

I believe that the consensus from the v2 comments at
<https://patchwork.kernel.org/patch/10727121/> are that this should
be:
compatible = "operating-points-v2-qcom-level", "operating-points-v2";
...same with the other one below...
