* 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>; };
