FYI the button layout on this device is different from common commercial
gamepads like XBox, Playstation and Logitech.
This seems to be common to all gamepads from Adafruit.
Adafruit:
X
Y A
B
Others:
Y
X B
A
In input-event-codes.h the symbol BTN_A actually maps to BTN_SOUTH,
matching the common layout. But as you can see this is wrong for this
device.
(Same for BTN_B and BTN_EAST)
Weirdly enough for BTN_X/BTN_NORTH and BTN_Y/BNT_WEST the aliasing is
correct for Adafruit and wrong for the others.
Not sure how to fix this correctly. Maybe the input maintainers know.
