Sony DualShock4 - basic functions work, but looking to improve support

Hi all,
I wanted to report that basic functions of the DualShock4 work under Linux
(USB connected), but I'd like to work on it to get everything working -
like we have on the DualShock3.

Attached are a couple of logs and the report descriptor.

Haptic/Rumble does not work, even though I have my machine patched to make
DualShock3 work.

If we look at the hidraw stream there's a lot (64 bytes) more there!

$ hexdump -v -e '64/1 "%02x " "\n"' < /dev/hidraw0

Anyone here want to collaborate?
