Yes, it seems for v8, v9 and v10 only the bindings were sent, even though the cover letter and subject say it's a series of two patches.

To my knowledge the latest version of the driver patch is this:

https://patchwork.kernel.org/patch/11439689/

I did not go back and check, but I recall there was review feedback that is not yet addressed.

I applied the patch here and checkpatch was not happy:
total: 14 errors, 22 warnings, 11 checks, 314 lines checked

Many of these are trivial indent or spaces used where tabs should be used.
These needs to be fixed before the driver will be applied.

And there was too much that I just did it while applying.
