Excellent, this is a nice early holiday present :)
I've just received a DualSense controller so I'll try to test this in
the coming days.

"hid-sony-playstation"? Not sure how much the input/hid tree
maintainers will want to force this, but the same problem is going to
show up for the hid-based XBox controller driver (hid-xbox, or hid-
microsoft-xbox?) as hid-microsoft is as busy as hid-sony.

I know it's not your job to handle those, but be careful with not
breaking the clone controllers. Plenty of folks use them, for better or
for worse.

Is the audio jack on the controller already supported, or would that be
part of the features that aren't supported yet?

Do you think you might be able to share the information regarding how
the cable pairing is done, so we can add this support to bluez? I'm
fine with only sharing the implementation if you prefer to give me the
details privately (or through my employer).

Cheers
