| | | | | | | | | | | We should not be forcing edge triggered interrupt, but rather let platform decide the kind of trigger it needs to use. Also, the driver is not quite safe with regard to edge-triggered interrupts as it does not try to kick the controller after requesting/enabling IRQ.

* Input: ar1021_i2c - fix too long name in driver's device tableDmitry Torokhov2017-04-141-1/+1
| | | | | | | | | | | | | | | | | | | The name field in structure i2c_device_id is 20 characters, and we expect it to be NULL-terminated, however we are trying to stuff it with 21 bytes and thus NULL-terminator is lost. This causes issues when one creates device with name "MICROCHIP_AR1021_I2C" as i2c core cuts off the last "C", and automatic module loading by alias does not work as result. The -I2C suffix in the device name is superfluous, we know what bus we are dealing with, so let's drop it. Also, no other driver uses capitals, and the manufacturer name is normally not included, except in very rare cases of incompatible name collisions.

* Input: xpad - support some quirky Xbox One padsCameron Gutman2017-04-111-13/+101
| | | | | | | | | | | | | | | | | | | | | | | There are several quirky Xbox One pads that depend on initialization packets that the Microsoft pads don't require. To deal with these, I've added a mechanism for issuing device-specific initialization packets using a VID/PID-based quirks list. For the initial set of init quirks, I have added quirk handling from Valve's Steam Link xpad driver[0] and the 360Controller project[1] for macOS to enable some new pads to work properly. This should enable full functionality on the following quirky pads: 0x0e6f:0x0165 - Titanfall 2 gamepad (previously fully non-functional) 0x0f0d:0x0067 - Hori Horipad (analog sticks previously non-functional) 0x24c6:0x541a - PowerA Xbox One pad (previously fully non-functional) 0x24c6:0x542a - PowerA Xbox One pad (previously fully non-functional) 0x24c6:0x543a - PowerA Xbox One pad (previously fully non-functional) [0]: https://github.com/ValveSoftware/steamlink-sdk/blob/master/kernel/drivers/input/joystick/xpad.c [1]: https://github.com/360Controller/360Controller Signed-off-by: Cameron Gutman <aicommander@gmail.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
