STMicroelectronics STM32 Timers PWM bindings
|
|
|
|
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: One or two <index level filter> to describe break input configurations.
|
|
"index" indicates on which break input (0 or 1) the configuration
|
|
should be applied.
|
|
"level" gives the active level (0=low or 1=high) of the input signal
|
|
for this configuration.
|
|
"filter" gives the filtering value to be applied.
|
|
|
|
Example:
|
|
timers@40010000 {
|
|
#address-cells = <1>;
|
|
#size-cells = <0>;
|
|
compatible = "st,stm32-timers";
|
|
reg = <0x40010000 0x400>;
|
|
clocks = <&rcc 0 160>;
|
|
clock-names = "int";
|
|
|
|
pwm {
|
|
compatible = "st,stm32-pwm";
|
|
pinctrl-0 = <&pwm1_pins>;
|
|
pinctrl-names = "default";
|
|
st,breakinput = <0 1 5>;
|
|
};
|
|
};
