[PATCH v6 0/5] Input: joystick: xpad: Add X-Box Adaptive Controller support

[PATCH v6 0/5] Input: joystick: xpad: Add X-Box Adaptive Controller support

[Nate Yocom]

Adds support for the X-Box Adaptive Controller, which is protocol
compatible with the XTYPE_XBOXONE support in the driver with two deltas:

 - The X-Box button sets 0x02 as its activation ID, where others set
   0x01
 - The controller has an additional Profile button with 4 active states,
   which this change maps to an Axis control with 4 possible values

Patch series adds device to the supported table, adds support for the
Profile button, and adds support for the X-Box button as distinct
changes.

[PATCH v6 2/5] Input: joystick: xpad: Add X-Box Adaptive XBox button

[Nate Yocom]

Adaptive controller sets 0x02 bit for this button, all others set 0x01
so presence of either is used for BTN_MODE.

This does not applies properly anymore on dtor/next [1] because of
90c9978959da ("Input: xpad - refactor using BIT() macro") and
e23c69e33248 ("Input: xpad - add support for XBOX One Elite paddles")

With that, please add:
