  SBUS input driver using
  This driver implements the SBUS protocol used on RC radio's
  to send out analogue joystick and switches output.
  SBUS is an single-wire inverted serial protocol so either you need to use
  the rx-invert feature of your serial driver or use an external signal inverter.
  The driver binds this to the Zephyr input system using INPUT_EV_CODES.

  The following examples defines a binding of 2 joysticks and a button using 5 channels.

  &lpuart6 {
    status = "okay";

    sbus {
        compatible = "futaba,sbus";
        right_stick_x {
            channel = <1>;
            type = <INPUT_EV_ABS>;
            zephyr,code = <INPUT_ABS_RX>;
        };
        right_stick_y {
            channel = <2>;
            type = <INPUT_EV_ABS>;
            zephyr,code = <INPUT_ABS_RY>;
        };

            channel = <3>;
