title: PWM Nexus node properties
|
|
|
|
description: >
|
|
Platforms can have a standardized connector/expansion slot that exposes PWMs
|
|
signals to expansion boards.
|
|
|
|
A nexus node allows to remap a phandle list in a consumer node through a
|
|
connector node in a generic way. With this remapping, the consumer node needs
|
|
to know only about the nexus node. Resources behind the nexus node are
|
|
decoupled by the nexus node itself.
