This information should be in the commit log. But I have a patch in the
pending branch which removes per_ce_irq:

[v2,2/2] ath10k: Get rid of "per_ce_irq" hw param

https://patchwork.kernel.org/patch/11654621/

So how will multilple hardware support work then?

In theory I like the patch but there's no information in the patch if
this works or breaks other hardware, especially QCA9884 or QCA6174 PCI
devices. I really need some kind of assurance that this works with all
ath10k devices, not just WCN3990 which you are working on.

I have written about this in the wiki:
