-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
-- #pwm-cells: Should be set to 3. This PWM chip uses the default 3 cells
- bindings defined in pwm.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";
- #pwm-cells = <3>;
- pinctrl-0 = <&pwm1_pins>;
- pinctrl-names = "default";
- st,breakinput = <0 1 5>;
- };
- };
