[RFC PATCH] HID: support the NACON / BigBen PS4 / PC Compact controller

[Giuseppe Bilotta <giuseppe.bilotta@gmail.com>]

---

I have recently come into possession of a NACON / Big Ben Interactive
USB wired PC Compact controller (USB vendor:device 146b:0603).
This is advertised as an «officially licensed PS4™ wired controller»
that «also boasts full compatibility with PC games».

It is supposed to be similar to a DualShock 4 controller except for the
lack of built-in speaker, light bar and “SIXAXIS” motion sensor.
In particular, in addition to the typical gamepad goodies, it has a
built-in touchpad and an audio jack.

As things are currently, the Linux kernel automatically matches it with
the xpad driver, that detects this as a “Generic X-Box controller”.
This kind of works, but in addition to minor issues such as the default
axis mapping being wrong (which could be fixed in the xpad driver),
the major downside for the xpad driver binding to the controller
is that it fails to expose the touchpad and the audio jack.

My hope was to let the xpad driver skip this device, and to manage it
through the hid subsystem, expecting the hid-sony and/or hid-playstation
drivers to be able to manage it.

However, I obviously don't understand enough about how the hid driver
manages the bindings, and so far I've been at a loss about making this
work. The hack to ignore the device in xpad works, although it's a
horrible hack that probably shouldn't be needed in the first place,
but the HID subsystem doesn't seem to pick up the device.
This patch is my very poor (and currently NOT WORKING) attempt,
and since I'm obviously going at this all wrong, I'd be glad for
any recommendations on how to approach this.

Cheers,

Giuseppe Bilotta
