-* Maxim MAX310X advanced Universal Asynchronous Receiver-Transmitter (UART)
-
-Required properties:
-- compatible: Should be one of the following:
- - "maxim,max3107" for Maxim MAX3107,
- - "maxim,max3108" for Maxim MAX3108,
- - "maxim,max3109" for Maxim MAX3109,
- - "maxim,max14830" for Maxim MAX14830.
-- reg: SPI chip select number.
-- interrupts: Specifies the interrupt source of the parent interrupt
- controller. The format of the interrupt specifier depends on the
- parent interrupt controller.
-- clocks: phandle to the IC source clock.
-- clock-names: Should be "xtal" if clock is an external crystal or
- "osc" if an external clock source is used.
-
-Optional properties:
-- gpio-controller: Marks the device node as a GPIO controller.
-- #gpio-cells: Should be two. The first cell is the GPIO number and
- the second cell is used to specify the GPIO polarity:
- 0 = active high,
- 1 = active low.
-
-Example:
-
-/ {
- clocks {
- spi_uart_clk: osc_max14830 {
- compatible = "fixed-clock";
- #clock-cells = <0>;
- clock-frequency = <3686400>;
- };
-
- };
-};
-
-&spi0 {
- max14830: max14830@0 {
- compatible = "maxim,max14830";
- reg = <0>;
- clocks = <&spi_uart_clk>;
- clock-names = "osc";
- interrupt-parent = <&gpio3>;
- interrupts = <7 IRQ_TYPE_LEVEL_LOW>;
- gpio-controller;
- #gpio-cells = <2>;
- };
