1* NXP SC16IS7xx advanced Universal Asynchronous Receiver-Transmitter (UART)
2* i2c as bus
3
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        };

36* spi as bus
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.

61Example:
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>;
68		gpio-controller;
69		#gpio-cells = <2>;
