+* STMicroelectronics STM32 USART
+
+Required properties:
+- compatible: Should be "st,stm32-usart"
+- reg: The address and length of the peripheral registers space
+- interrupts: The interrupt line of the USART instance
+- clocks: The input clock of the USART instance
+- pinctrl: The reference on the pins configuration
+
+Example:
+usart1: usart@40011000 {
+	compatible = "st,stm32-usart";
+	reg = <0x40011000 0x400>;
+	interrupts = <37>;
+	clocks = <&clk_pclk2>;
+	pinctrl-names = "default";
+	pinctrl-0 = <&pinctrl_usart1>;
