* NXP LPC1850 UART
Required properties:
- compatible : "nxp,lpc1850-uart", "ns16550a".
- reg : offset and length of the register set for the device.
- interrupts : should contain uart interrupt.
- clocks : phandle to the input clocks.
- clock-names : required elements: "uartclk", "reg".
Optional properties:
- dmas : Two or more DMA channel specifiers following the
convention outlined in bindings/dma/dma.txt
- dma-names : Names for the dma channels, if present. There must
be at least one channel named "tx" for transmit
and named "rx" for receive.
Since it's also possible to also use the of_serial.c driver all
parameters from 8250.txt also apply but are optional.
Example:
