Define bindings for pwm-stm32
version 6:
- change st,breakinput parameter format to make it usuable on stm32f7 too.
version 2:
- use parameters instead of compatible of handle the hardware configuration

+Must be a sub-node of an STM32 Timers device tree node. +See ../mfd/stm32-timers.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: Arrays of three u32 <index level filter> to describe break input configurations.
"index" indicates on which break input the configuration should be applied.
"level" gives the active level (0=low or 1=high) for this configuration.
"filter" gives the filtering value to be applied.
+Example:
- timers@40010000 {
timer@...
No, it should be timers.
The 's' is intentional, since this parent (MFD) device houses 3 different types of timers. The "timer" node is a child of this one.
With that,
