1* NXP LPC1850 UART 2 3Required 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 10Optional 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 17Since it's also possible to also use the of_serial.c driver all 18parameters from 8250.txt also apply but are optional. 19 20Example: 21uart0: 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}; 29
