-STMicroelectronics PWM driver bindings
---------------------------------------
-
-Required parameters:
-- compatible : "st,pwm"
-- #pwm-cells : Number of cells used to specify a PWM. First cell
- specifies the per-chip index of the PWM to use and the
- second cell is the period in nanoseconds - fixed to 2
- for STiH41x.
-- reg : Physical base address and length of the controller's
- registers.
-- pinctrl-names: Set to "default".
-- pinctrl-0: List of phandles pointing to pin configuration nodes
- for PWM module.
- For Pinctrl properties, please refer to [1].
-- clock-names: Valid entries are "pwm" and/or "capture".
-- clocks: phandle of the clock used by the PWM module.
- For Clk properties, please refer to [2].
-- interrupts: IRQ for the Capture device
-
-Optional properties:
-- st,pwm-num-chan: Number of available PWM channels. Default is 0.
-- st,capture-num-chan: Number of available Capture channels. Default is 0.
