Platforms can have a standardized connector/expansion slot that exposes
signals like PWMs to expansion boards in an SoC agnostic way.
The support for nexus node [1] has been added to handle those cases in
commit bd6f2fd5a1d5 ("of: Support parsing phandle argument lists through
a nexus node") and the gpio subsystem adopted the support in commit
c11e6f0f04db ("gpio: Support gpio nexus dt bindings")
Add support for nexus node dt binding in the pwm subsystem.
