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- interrupts: Should contain the UART interrupt
14- clocks: Reference to the IC source clock.
15	OR (when there is no clock provider visible to the platform)
16- clock-frequency: The source clock frequency for the IC.
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        };
35
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- interrupts: Specifies the interrupt source of the parent interrupt
48  controller. The format of the interrupt specifier depends on the
49  parent interrupt controller.
50- clocks: phandle to the IC source clock.
51
52Optional properties:
53- gpio-controller: Marks the device node as a GPIO controller.
54- #gpio-cells: Should be two. The first cell is the GPIO number and
55  the second cell is used to specify the GPIO polarity:
56    0 = active high,
57    1 = active low.
58
59Example:
60	sc16is750: sc16is750@0 {
61		compatible = "nxp,sc16is750";
62		reg = <0>;
63		clocks = <&clk20m>;
64		interrupt-parent = <&gpio3>;
65		interrupts = <7 IRQ_TYPE_EDGE_FALLING>;
66		gpio-controller;
67		#gpio-cells = <2>;
