* Input: xpad - remove unused functionArnd Bergmann2016-01-281-1/+0
| | | | | | | | | | | | | There are two definitions of xpad_identify_controller(), one is used when CONFIG_JOYSTICK_XPAD_LEDS is set, but the other one is empty and never used, and we get a gcc warning about it: drivers/input/joystick/xpad.c:1210:13: warning: 'xpad_identify_controller' defined but not used [-Wunused-function] This removes the second definition.

| * Input: xpad - use LED API when identifying wireless controllersDmitry Torokhov2016-01-041-1/+1
| | | | | | | | | | | | | | | | When lighting up the segment identifying wireless controller, Instead of sending command directly to the controller, let's do it via LED API (usinf led_set_brightness) so that LED object state is in sync with controller state and we'll light up the correct segment on resume as well.

| * Input: xpad - workaround dead irq_out after suspend/ resumePavel Rojtberg2016-01-041-38/+137
| | | | | | | | | | | | | | | | | | | | | | | | The irq_out urb is dead after suspend/ resume on my x360 wr pad. (also reproduced by Zachary Lund [0]) Work around this by implementing suspend, resume, and reset_resume callbacks and properly shutting down URBs on suspend and restarting them on resume.

| * Input: xpad - update Xbox One Force Feedback SupportPierre-Loup A. Griffais2016-01-041-5/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There's apparently a serial number woven into both input and output packets; neglecting to specify a valid serial number causes the controller to ignore the rumble packets. The scale of the rumble was also apparently halved in the packets. The initialization packet had to be changed to allow force feedback to work. see https://github.com/paroj/xpad/issues/7 for details.

| * Input: xpad - correctly handle concurrent LED and FF requestsPavel Rojtberg2016-01-041-99/+223
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Track the status of the irq_out URB to prevent submission iof new requests while current one is active. Failure to do so results in the "URB submitted while active" warning/stack trace. Store pending brightness and FF effect in the driver structure and replace it with the latest requests until the device is ready to process next request. Alternate serving LED vs FF requests to make sure one does not starve another. See [1] for discussion. Inspired by patch of Sarah Bessmer [2].

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Handle the "a new device is present" message properly by dynamically creating the input device at this point in time. This means we now do not "preallocate" all 4 devices when a single wireless base station is seen. This requires a workqueue as we are in interrupt context when we learn about this. Also properly disconnect any devices that we are told are removed. Signed-off-by: "Pierre-Loup A.

| * Input: xpad - remove spurious events of wireless xpad 360 controllerClement Calmels2015-12-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When powering up a wireless xbox 360 controller, some wrong joystick events are generated. It is annoying because, for example, it makes unwanted moves in Steam big picture mode's menu. When my controller is powering up, this packet is received by the driver: 00000000: 00 0f 00 f0 00 cc ff cf 8b e0 86 6a 68 f0 00 20 ...........jh.. 00000010: 13 e3 20 1d 30 03 40 01 50 01 ff ff .. .0.@.P... According to xboxdrv userspace driver source code, this packet is only dumping a serial id and should not be interpreted as joystick events. This issue can be easily seen with jstest: $ jstest --event /dev/input/js0 This patch only adds a way to filter out this "serial" packet and as a result it removes the spurous events.

* Input: xpad - x360w: report dpad as buttons and axesPavel Rojtberg2015-10-101-2/+20
| | | | | | | | | | | | | | | as discussed here[0], x360w is the only pad that maps dpad_to_button. This is bad for downstream developers as they have to differ between x360 and x360w which is not intuitive. This patch implements the suggested solution of exposing the dpad both as axes and as buttons. This retains backward compatibility with software already dealing with the difference while makes new software work as expected across x360/ x360w pads.

* Input: xpad - remove needless bulk out URB used for LED setupPavel Rojtberg2015-10-101-78/+1
| | | | | | | | | | | | | This code was probably wrong ever since and is redundant with xpad_send_led_command. Both try to send a similar command to the xbox360 controller. However xpad_send_led_command correctly uses the pad_nr instead of bInterfaceNumber to select the led and re-uses the irq_out URB instead of creating a new one. Note that this change only affects the two supported wireless controllers. Tested using the xbox360 wireless controller (PC).

* Input: xpad - use ida() for finding the pad_nrPavel Rojtberg2015-10-101-12/+20
| | | | | | | | | | | | | | | | | | | The pad_nr corresponds to the lit up LED on the controller. Therefore there should be no gaps when enumerating. Currently a LED is only re-assigned after a controller is re-connected 4 times. This patch uses ida to track connected pads - this way we can re-assign freed up pad number immediately. Consider the following case: 1. pad A is connected and gets pad_nr = 0 2. pad B is connected and gets pad_nr = 1 3. pad A is disconnected 4. pad A is connected again using ida_simple_get() controller A now correctly gets pad_nr = 0 again.
