Required properties:

- compatible: Can be either "st,stm32-usart", "st,stm32-uart",

"st,stm32f7-usart" or "st,stm32f7-uart" depending on whether

the device supports synchronous mode and is compatible with

stm32(f4) or stm32f7.

- compatible: can be either:

  - "st,stm32-usart",

  - "st,stm32-uart",

  - "st,stm32f7-usart",

  - "st,stm32f7-uart",

  - "st,stm32h7-usart"

  - "st,stm32h7-uart".

  depending on whether the device supports synchronous mode

  and is compatible with stm32(f4), stm32f7 or stm32h7.

- reg: The address and length of the peripheral registers space

- interrupts: The interrupt line of the USART instance

- interrupts:

  - The interrupt line for the USART instance,

  - An optional wake-up interrupt.

- clocks: The input clock of the USART instance
