+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@...23810 {
+ #reset-cells = <1>;
+ compatible = "st,stm32-reset";
+ reg = <0x40023810 0x4>;
+};
+
+Specifying softreset control of devices
+=======================================
+
+Device nodes should specify the reset channel required in their "resets"
+property, containing a phandle to the reset device node and an index specifying
+which channel to use, as described in reset.txt
+
+example:
+
+ timer2 {
+ resets = <&resets TIM2_RESET>;
+ };
+
+Macro definitions for the supported reset channels can be found in:
+
+include/dt-bindings/reset/st,stm32f429.h
