version 2:
- use parameters instead of compatible of handle the hardware configuration

+STMicroelectronics STM32 General Purpose Timer PWM bindings
+
+Must be a sub-node of an STM32 General Purpose Timer device tree node.
+See ../mfd/stm32-general-purpose-timer.txt for details about the parent node.
+
+Required parameters:
+- compatible:  Must be "st,stm32-pwm".
+- pinctrl-names:   Set to "default".
+- pinctrl-0:   List of phandles pointing to pin configuration nodes 
for PWM module.
+   For Pinctrl properties see 
../pinctrl/pinctrl-bindings.txt
+
+Optional parameters:
+- st,breakinput-polarity: If present, a break input is available
+for the channel. In that case the property value denotes the
+polarity of the break input:
+- 0: active low
+- 1: active high
+
+Example:
+   timers@4001 {
+   #address-cells = <1>;
+   #size-cells = <0>;
+   compatible = "st,stm32-gptimer";
+   reg = <0x4001 0x400>;
