4Required properties:
5- compatible: Should be one of the following:
6 - "nxp,sc16is740" for NXP SC16IS740,
7 - "nxp,sc16is741" for NXP SC16IS741,
8 - "nxp,sc16is750" for NXP SC16IS750,
9 - "nxp,sc16is752" for NXP SC16IS752,
10 - "nxp,sc16is760" for NXP SC16IS760,
11 - "nxp,sc16is762" for NXP SC16IS762.
12- reg: I2C address of the SC16IS7xx device.
13- interrupt-parent: The phandle for the interrupt controller that
14 services interrupts for this IC.
15- interrupts: Should contain the UART interrupt
16- clocks: Reference to the IC source clock.
17
18Optional properties:
19- gpio-controller: Marks the device node as a GPIO controller.
20- #gpio-cells: Should be two. The first cell is the GPIO number and
21 the second cell is used to specify the GPIO polarity:
22 0 = active high,
23 1 = active low.
24
25Example:
26 sc16is750: sc16is750@51 {
27 compatible = "nxp,sc16is750";
28 reg = <0x51>;
29 clocks = <&clk20m>;
30 interrupt-parent = <&gpio3>;
31 interrupts = <7 IRQ_TYPE_EDGE_FALLING>;
32 gpio-controller;
33 #gpio-cells = <2>;
34 };

37
38Required properties:
39- compatible: Should be one of the following:
40 - "nxp,sc16is740" for NXP SC16IS740,
41 - "nxp,sc16is741" for NXP SC16IS741,
42 - "nxp,sc16is750" for NXP SC16IS750,
43 - "nxp,sc16is752" for NXP SC16IS752,
44 - "nxp,sc16is760" for NXP SC16IS760,
45 - "nxp,sc16is762" for NXP SC16IS762.
46- reg: SPI chip select number.
47- interrupt-parent: The phandle for the interrupt controller that
48 services interrupts for this IC.
49- interrupts: Specifies the interrupt source of the parent interrupt
50 controller. The format of the interrupt specifier depends on the
51 parent interrupt controller.
52- clocks: phandle to the IC source clock.
53
54Optional properties:
55- gpio-controller: Marks the device node as a GPIO controller.
56- #gpio-cells: Should be two. The first cell is the GPIO number and
57 the second cell is used to specify the GPIO polarity:
58 0 = active high,
59 1 = active low.

62 sc16is750: sc16is750@0 {
63 compatible = "nxp,sc16is750";
64 reg = <0>;
65 clocks = <&clk20m>;
66 interrupt-parent = <&gpio3>;
67 interrupts = <7 IRQ_TYPE_EDGE_FALLING>;
