    1 * NXP LPC1850 UART
    2 
    3 Required properties:
    4 - compatible    : "nxp,lpc1850-uart", "ns16550a".
    5 - reg           : offset and length of the register set for the device.
    6 - interrupts    : should contain uart interrupt.
    7 - clocks        : phandle to the input clocks.
    8 - clock-names   : required elements: "uartclk", "reg".
    9 
   10 Optional properties:
   11 - dmas          : Two or more DMA channel specifiers following the
   12                   convention outlined in bindings/dma/dma.txt
   13 - dma-names     : Names for the dma channels, if present. There must
   14                   be at least one channel named "tx" for transmit
   15                   and named "rx" for receive.
   16 
   17 Since it's also possible to also use the of_serial.c driver all
   18 parameters from 8250.txt also apply but are optional.
   19 
   20 Example:
   21 uart0: serial@40081000 {
   22         compatible = "nxp,lpc1850-uart", "ns16550a";
   23         reg = <0x40081000 0x1000>;
   24         reg-shift = <2>;
   25         interrupts = <24>;
   26         clocks = <&ccu2 CLK_APB0_UART0>, <&ccu1 CLK_CPU_UART0>;
   27         clock-names = "uartclk", "reg";
   28 };
