dt-bindings: input: bindings for Adafruit Seesaw Gamepad
Adds bindings for the Adafruit Seesaw Gamepad.
The gamepad functions as an i2c device with the default address of 0x50
and has an IRQ pin that can be enabled in the driver to allow for a rising
edge trigger on each button press or joystick movement.
