+STM32 Timers driver bindings
+
+This IP provides 3 types of timer along with PWM functionality:
+- advanced-control timers consist of a 16-bit auto-reload counter driven by a programmable
+ prescaler, break input feature, PWM outputs and complementary PWM ouputs channels.
+- general-purpose timers consist of a 16-bit or 32-bit auto-reload counter driven by a
+ programmable prescaler and PWM outputs.
+- basic timers consist of a 16-bit auto-reload counter driven by a programmable prescaler.
+
+Required parameters:
+- compatible: must be "st,stm32-timers"
+
+- reg: Physical base address and length of the controller's
+ registers.
+- clock-names: Set to "int".
+- clocks: Phandle to the clock used by the timer module.
+ For Clk properties, please refer to ../clock/clock-bindings.txt
+
+Optional parameters:
+- resets: Phandle to the parent reset controller.
+ See ../reset/st,stm32-rcc.txt
+
+Optional subnodes:
+- pwm: See ../pwm/pwm-stm32.txt
+- timer: See ../iio/timer/stm32-timer-trigger.txt
+
+Example:
+ timers@40010000 {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ compatible = "st,stm32-timers";
+ reg = <0x40010000 0x400>;
+ clocks = <&rcc 0 160>;
+ clock-names = "clk_int";
+
+ pwm {
+ compatible = "st,stm32-pwm";
+ pinctrl-0 = <&pwm1_pins>;
+ pinctrl-names = "default";
+ };
+
+ timer@0 {
+ compatible = "st,stm32-timer-trigger";
+ reg = <0>;
+ };
+ };
