I did some major refactoring¹ on the v4 patch series and am currently
providing it for Arch Linux as a DKMS package in the AUR².
A teensy bit of my changes seems to have influenced the v5 version but
I actually did some major changes, like strictly separating the HID,
platform and PCI driver parts.
I did not submit my changes for upstream so far, since I do not want to
undermine AMD's work on this nor cause competing driver
implementations.

Sincerely,

Richard
