+* 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.
+- 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
+
+Optional properties:
+- pinctrl: The reference on the pins configuration
+- st,hw-flow-ctrl: bool flag to enable hardware flow control.
+
+Examples:
+usart4: serial@40004c00 {
+ compatible = "st,stm32-uart";
+ reg = <0x40004c00 0x400>;
+ interrupts = <52>;
+ clocks = <&clk_pclk1>;
+ pinctrl-names = "default";
+ pinctrl-0 = <&pinctrl_usart4>;
+};
+
+usart2: serial@40004400 {
+ compatible = "st,stm32-usart", "st,stm32-uart";
+ reg = <0x40004400 0x400>;
+ interrupts = <38>;
+ clocks = <&clk_pclk1>;
+ st,hw-flow-ctrl;
+ pinctrl-names = "default";
+ pinctrl-0 = <&pinctrl_usart2 &pinctrl_usart2_rtscts>;
+};
