+STMicroelectronics STM32 Peripheral Reset Controller
+====================================================
+
+Please also refer to reset.txt in this directory for common reset
+controller binding usage.
+
+Required properties:
+- compatible: Should be "st,stm32-reset"
+- reg: should be register base and length as documented in the
+  datasheet
+- #reset-cells: 1, see below
+
+example:
+
+reset_ahb1: reset@40023810 {
+	#reset-cells = <1>;
+	compatible = "st,stm32-reset";
+	reg = <0x40023810 0x4>;
+};
