Date
From: Fabrice Gasnier <fabrice.gasnier@st.com>

Introduce new compatibles for "st,stm32h7-usart" and "st,stm32h7-uart".
This new compatible allow to use optional wake-up interrupt.

* 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
