The ADP5585 is a 10/11 input/output port expander with a built in keypad
matrix decoder, programmable logic, reset generator, and PWM generator.
This driver supports the PWM function using the platform device
registered by the core MFD driver.
The driver is derived from an initial implementation from NXP, available
in commit 113113742208 ("MLK-25922-1 pwm: adp5585: add adp5585 PWM
support") in their BSP kernel tree. It has been extensively rewritten.

|
Generic Pulse-Width Modulation (PWM) support.
|
|
|
|
In Pulse-Width Modulation, a variation of the width of pulses
|
|
in a rectangular pulse signal is used as a means to alter the
|
|
average power of the signal. Applications include efficient
|
|
power delivery and voltage regulation. In computer systems,
|
|
PWMs are commonly used to control fans or the brightness of
|
|
display backlights.
|
|
|
|
This framework provides a generic interface to PWM devices
|
|
within the Linux kernel. On the driver side it provides an API
|
|
to register and unregister a PWM chip, an abstraction of a PWM
|
|
controller, that supports one or more PWM devices. Client
|
|
drivers can request PWM devices and use the generic framework
|
|
to configure as well as enable and disable them.
|
|
|
|
This generic framework replaces the legacy PWM framework which
|
|
allows only a single driver implementing the required API. Not
|
|
all legacy implementations have been ported to the framework
|
|
yet. The framework provides an API that is backward compatible
|
|
with the legacy framework so that existing client drivers
|
|
continue to work as expected.
|
|
|
|
If unsure, say no.
