* Energymicro efm32 UART
Required properties:
- compatible : Should be "energymicro,efm32-uart"
- reg : Address and length of the register set
- interrupts : Should contain uart interrupt
Optional properties:
- energymicro,location : Decides the location of the USART I/O pins.
Allowed range : [0 .. 5]
Default: 0
Example:
uart@4000c400 {
compatible = "energymicro,efm32-uart";
reg = <0x4000c400 0x400>;
interrupts = <15>;
energymicro,location = <0>;
};
