* 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.
- interrupt-parent: The phandle for the interrupt controller that
services interrupts for this IC.
- 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.
