Since merge of tty-6.0-rc1, "make htmldocs" with Sphinx >=3.1 emits
a bunch of warnings indicating duplicate kernel-doc comments from
drivers/tty/serial/serial_core.c.
This is due to the kernel-doc directive for serial_core.c in
serial/drivers.rst added in the merge. It conflicts with an existing
kernel-doc directive in miscellaneous.rst.
Remove the latter directive and resolve the duplicates.

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