     25Pulse-Width Modulation (PWM)
     26============================
     27
     28Pulse-width modulation is a modulation technique primarily used to
     29control power supplied to electrical devices.
     30
     31The PWM framework provides an abstraction for providers and consumers of
     32PWM signals. A controller that provides one or more PWM signals is
     33registered as :c:type:`struct pwm_chip <pwm_chip>`. Providers
     34are expected to embed this structure in a driver-specific structure.
     35This structure contains fields that describe a particular chip.
     36
     37A chip exposes one or more PWM signal sources, each of which exposed as
     38a :c:type:`struct pwm_device <pwm_device>`. Operations can be
     39performed on PWM devices to control the period, duty cycle, polarity and
     40active state of the signal.
     41
     42Note that PWM devices are exclusive resources: they can always only be
     43used by one consumer at a time.
