Oh, in that case you should probably go "all out" and ask on the 
LKML to remove all of the ath9k and ath10k ahb work. From what I
know all the "users" are running some sort of OpenWRT/LEDE or a 
derivative. This is because Atheros/QCA provided a SDK based on
OpenWRT.

Alban has been trying to convert the platform to device-tree
and add them to the mainline for a while now:
 
https://patchwork.kernel.org/patch/6514551/

So, you are questioning this work as well.

Not at all. Ralph Sennhauser has been doing a great job of getting all
the Marvell devices into Mainline, and i help as much as i can, being
one of the Marvell SoC Maintainers.

I'm just saying, get a few boards which require these facilities into
the mainline, and then you have a much stranger base to argue from.
