* NXP SC16IS7xx advanced Universal Asynchronous Receiver-Transmitter (UART)



Required properties:

- compatible: Should be one of the following:

  - "nxp,sc16is740" for NXP SC16IS740,

  - "nxp,sc16is741" for NXP SC16IS741,

  - "nxp,sc16is750" for NXP SC16IS750,

  - "nxp,sc16is752" for NXP SC16IS752,

  - "nxp,sc16is760" for NXP SC16IS760,

  - "nxp,sc16is762" for NXP SC16IS762.

- reg: I2C address of the SC16IS7xx device.

- interrupt-parent: The phandle for the interrupt controller that

  services interrupts for this IC.

- interrupts: Should contain the UART interrupt

- clocks: Reference to the IC source clock.



Optional properties:

- gpio-controller: Marks the device node as a GPIO controller.

- #gpio-cells: Should be two. The first cell is the GPIO number and

  the second cell is used to specify the GPIO polarity:

    0 = active high,

    1 = active low.



Example:

        sc16is750: sc16is750@51 {

                compatible = "nxp,sc16is750";

                reg = <0x51>;

                clocks = <&clk20m>;

                interrupt-parent = <&gpio3>;

                interrupts = <7 IRQ_TYPE_EDGE_FALLING>;

                gpio-controller;

                #gpio-cells = <2>;

        };
