[PATCH 0/5] Support for the Sony Motion Controller and other cleanups

[PATCH 0/5] Support for the Sony Motion Controller and other cleanups

[Frank Praznik]

This set of patches adds initial support for the Sony Motion Controller via
cleaned-up initial patches from Pavel Machek, streamlines LED initialization
and state updates, adds a comment to explain why the Sixaxis has so many axes
and why they spill over into the multi-touch space and makes some general
cosmetic corrections.

Pavel, could you test the motion controller patches?  I didn't alter the basic
logic from your patch so everything should work, but I'd like to make sure.

[PATCH 1/5] hid: sony: Add the product ID for the Sony Motion Controller

[Frank Praznik]

Adds the PID for the Sony motion controller to the hardware ID list.

[PATCH 2/5] hid: sony: Add support for the Sony Motion Controller

[Frank Praznik]

Add a fixed-up HID descriptor for the Sony motion controller and enable
controls for the LED light as well as force-feedback.

The LED is multi-colored (red, green, blue) and has a 'global' control to
allow it to be flashed or switched on an off atomically.

The motion controller has a single rumble motor so the higher of the left and
right values is used to set the speed.

 Pavel, can you please test this and make sure it works?  

 This is basically Pavel's patch with the unrelated changes removed and a bit
 of additional functionality added.

 A 'global' LED control has been added to facilitate blinking and otherwise
 toggling the whole light on and off like on the Dualshock 4.

 It also adds rumble support since the device seems to support it.  The device
 only has one rumble motor so the higher of the left and right values is used
 to set the speed.  Both must be zero to stop the effect.

[PATCH 4/5] hid: sony: Simplify LED initialization and eliminate redundant copies when updating LED states

[Frank Praznik]

Directly set the initial LED states in the device state struct instead
of copying them from a temporary array.

This allows for the removal of a redundant "x = x" copy loop in
sony_set_leds() that was taking place any time an LED was updated.

It also allows for the simplifying of the parameters in functions dealing
with LED initialization and updates since only a pointer to the sony_sc
struct is needed now.

Signed-off-by: Frank Praznik <frank.praznik@oh.rr.com>

 This completely removes the mostly useless loop in sony_set_leds() and
 streamlines other LED related functions in the process.

[PATCH 5/5] hid: sony: Correct a typo in a HID descriptor comment and explain the odd Sixaxis axis mapping

[Frank Praznik]

Correct a spelling mistake in the Sixaxis HID descriptor comment.

Add an explanation as to why the Sixaxis has so many analog axes and why
some of them are seen as multi-touch axes.

Oh... I don't think the global control at this level is good idea. Let
me test how it works, but assigning different triggers to global and
red would be interesting, for example.

Ok, that one was easy.

Now it registers but the LEDs do not light.

Ok, I spoke too fast. It does work, somehow, as long as I keep the
global control on (with the kmalloc fix).

But for example this does not produce the desired result:

root@duo:/sys/class/leds/0003:054C:03D5.0002:global# echo hearbeat >
trigger
root@duo:/sys/class/leds/0003:054C:03D5.0002:global# cd ..
root@duo:/sys/class/leds# cd 0003\:054C\:03D5.0002\:red
root@duo:/sys/class/leds/0003:054C:03D5.0002:red# cat brightness
255
root@duo:/sys/class/leds/0003:054C:03D5.0002:red#

(Hm. It sometimes works somehow. Weird.)

Yes, I believe we should eventually support RGB ways in some nice way,
but no, having "global" LED "and-ed" with the color LEDs does not seem
like a good way to me. The "global" brightness is ignored, only zero /
non zero matters. It is not a real LED.

RGB support should really be done at LED core, as more than one driver
needs it.

Not sure how this is expected to work. I tried: (and did not get any
vibrations).

Thanks,

Hmm. Seems I tried wrong device. But no vibrations with the right

If it has just one motor, should it say so in the description? Not
advertising both heavy and light motor.

If I do this, I can control vibrations using the "red" led. Value of
70 is lowest that produces anything...

Umm. Using echo with fftest was not good idea. Using it from command
line, it works normally.

Thanks and sorry for confusion,

Ack, sorry about that mistake.  On the plus side, it uncovered a 
mishandled failure path in the initialization function.  I'll add a 
patch for that in v2 of the series.

The FF_RUMBLE flag exposes two motors by default and there doesn't seem 
to be a way to change it.

This is how the Wiimote with a single motor works (FF_RUMBLE and 
treating the strong/weak motors as one).  Would one of the other effects 
be more suitable?

I don't know enough about the force feedback subsystem, sorry. I guess
it is okay as it is, then... Thanks for all the work!
