5   An external clock signal driven by a PWM pin.
7   The devicetree must define a clock node:
11       compatible = "pwm-clock";
12       #clock-cells = <1>;
16   This will create a device node with a clock-controller
17   API. Internally the device node will use PWM API to start the
18   clock signals at 1MHz. Note that the PWM_HZ() macro converts the
20   errors if the clock frequency is not an integer number of nanoseconds.
21   The clock frequency can be explicitly set using the clock-frequency
24   The PWM node may need to be properly configured to generate
26   for the target PWM driver.

43   pwm-on-delay:
47       Optional blocking delay in micro seconds to make sure that the PWM
48       clock has started after returning from clock_control_on().
