Fwd: AX500 support quirks

[Patricio Ferraggi Ares]

Hey folks,

So. I am still using arch linux, although it is a tricky situation. I
have wifi working (as long as I boot with fallback initramfs and don't
update my system), still no Bluetooth. I am currently using a bt
dongle to cover that.

I have decided to give it a try and dive deeper by tying to compile my
own kernel with the necessary modules and firmware for Wifi and
Bluetooth.

Could you guys share with me on which repos (apart from the kernel
source) I should use in order to build something based on the latest
linux-mainline kernel?
I am unaware of how should I include the latest ath11k drivers from
Kalle and which modules I need in order to make BT work.

I would really appreciate it if you could give me some links to the
repos, some info, and maybe a basic strategy on how to approach this.
I will search and learn from that starting point.

Thanks for all your help.
