1* NXP SC16IS7xx advanced Universal Asynchronous Receiver-Transmitter (UART)
2
3Required properties:
4- compatible: Should be one of the following:
5  - "nxp,sc16is740" for NXP SC16IS740,
6  - "nxp,sc16is741" for NXP SC16IS741,
7  - "nxp,sc16is750" for NXP SC16IS750,
8  - "nxp,sc16is752" for NXP SC16IS752,
9  - "nxp,sc16is760" for NXP SC16IS760,
10  - "nxp,sc16is762" for NXP SC16IS762.
11- reg: I2C address of the SC16IS7xx device.
12- interrupt-parent: The phandle for the interrupt controller that
13  services interrupts for this IC.
14- interrupts: Should contain the UART interrupt
15- clocks: Reference to the IC source clock.
16
17Optional properties:
18- gpio-controller: Marks the device node as a GPIO controller.
19- #gpio-cells: Should be two. The first cell is the GPIO number and
20  the second cell is used to specify the GPIO polarity:
21    0 = active high,
22    1 = active low.

24Example:
25        sc16is750: sc16is750@51 {
26                compatible = "nxp,sc16is750";
27                reg = <0x51>;
28                clocks = <&clk20m>;
29                interrupt-parent = <&gpio3>;
30                interrupts = <7 IRQ_TYPE_EDGE_FALLING>;
31                gpio-controller;
32                #gpio-cells = <2>;
33        };
