* Freescale low power universal asynchronous receiver/transmitter (lpuart)

Required properties:
- compatible : Should be "fsl,<soc>-lpuart"
- reg : Address and length of the register set for the device
- interrupts : Should contain uart interrupt

Example:

uart0: serial@40027000 {
	       compatible = "fsl,vf610-lpuart";
	       reg = <0x40027000 0x1000>;
	       interrupts = <0 61 0x00>;
       };
