Subject: Fun with sony motion controllers: navigation controller

Hi!

After oopsing kernel with ps/3 peripherals, I decided to play some
more.

First "sony motion controller" (part of ps/3 move without the
led). Good news is that it no longer oopses. After pressing the PS
button, it seems to work, but it produces endless stream of events in
evtest:

Event: time 1426360519.967818, type 3 (EV_ABS), code 0 (ABS_X), value 131
Event: time 1426360519.967818, type 3 (EV_ABS), code 1 (ABS_Y), value 129
Event: time 1426360519.967818, type 3 (EV_ABS), code 59 (ABS_MT_DISTANCE), value 513
Event: time 1426360519.967818, type 3 (EV_ABS), code 60 (ABS_MT_TOOL_X), value 513

Should it really produce multitouch events?

Force feedback does not seem to work:

root@amd:~# fftest /dev/input/event7
Force feedback test program.

Device /dev/input/event7 opened

Uploading effect #4 (Strong rumble, with heavy motor) ... Error: Function not implemented
Uploading effect #5 (Weak rumble, with light motor) ... Error: Function not implemented
Enter effect number, -1 to exit

Battery status reporting seems to work. Unfortunately, desktop (Mate on
Debian 8) seems to think it is system battery, and acts funny.
