Hello Arnd! May you please spare AAT2870 from being removed? I have a
device which uses aat2870 (LG Optimus 2X P990 Tegra 2, not upstreamed
yet, but in process as well) and atm I am working on converting this
driver to use OF. Thank you!

Sure, I have removed this patch from my series now.

Thank you!

P. S. If you are planning to remove more old drivers, please CC me in
since I may be interested in some additional driver upgrades for
devices I own.

Please have a look at

https://git.kernel.org/pub/scm/linux/kernel/git/soc/soc.git/log/?h=board-remove-7.3

Thanks, I will keep my eye on this branch.

I tried to be careful about figuring out exactly which drivers are
unused, but I'm sure there are still a few false positive and false
negative ones in there. I've added the current list of driver files below,
let me know if you see something that shouldn't be there.

LM3532 has full OF support and is functional, it just does not have

(Tegra 2 based).

Here is commit removing LM3532
