title: AWINIC AW2016 3-channel LED Driver
maintainers:
- Kamal Wadhwa <quic_kamalw@quicinc.com>
description: |
AW2016 LED device supports 3 LED channels and the driver
register each channel as a single LED class device and
exports interfaces to update brightness, set timer trigger
and enable HW based blink functionalities.
