* STMicroelectronics STM32 USART
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
