1 * Cirrus Logic CLPS711X Universal Asynchronous Receiver/Transmitter (UART)
4 - compatible: Should be "cirrus,clps711x-uart".
5 - reg: Address and length of the register set for the device.
6 - interrupts: Should contain UART TX and RX interrupt.
7 - clocks: Should contain UART core clock number.
8 - syscon: Phandle to SYSCON node, which contain UART control bits.
11 - {rts,cts,dtr,dsr,rng,dcd}-gpios: specify a GPIO for RTS/CTS/DTR/DSR/RI/DCD
14 Note: Each UART port should have an alias correctly numbered
