1* Maxim MAX310X advanced Universal Asynchronous Receiver-Transmitter (UART)
2
3Required properties:
4- compatible: Should be one of the following:
5 - "maxim,max3107" for Maxim MAX3107,
6 - "maxim,max3108" for Maxim MAX3108,
7 - "maxim,max3109" for Maxim MAX3109,
8 - "maxim,max14830" for Maxim MAX14830.
9- reg: SPI chip select number.
10- interrupts: Specifies the interrupt source of the parent interrupt
11 controller. The format of the interrupt specifier depends on the
12 parent interrupt controller.
13- clocks: phandle to the IC source clock.
14- clock-names: Should be "xtal" if clock is an external crystal or
15 "osc" if an external clock source is used.
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:

26/ {
27 clocks {
28 spi_uart_clk: osc_max14830 {
29 compatible = "fixed-clock";
30 #clock-cells = <0>;
31 clock-frequency = <3686400>;
32 };
33
34 };
35};
36
37&spi0 {
38 max14830: max14830@0 {
39 compatible = "maxim,max14830";
40 reg = <0>;
41 clocks = <&spi_uart_clk>;
42 clock-names = "osc";
43 interrupt-parent = <&gpio3>;
44 interrupts = <7 IRQ_TYPE_LEVEL_LOW>;
45 gpio-controller;
46 #gpio-cells = <2>;
47 };
