This is a part of device tree bindings for Maxim MAX77693 MicroUSB Integrated
|
|
Circuit (MUIC).
|
|
|
|
There are two LED outputs available - FLED1 and FLED2. Each of them can
|
|
control a separate LED or they can be connected together to double the
|
|
maximum current for a single connected LED. One LED is represented by one
|
|
child node.
|
|
|
|
See also Documentation/devicetree/bindings/mfd/maxim,max77693.yaml for
|
|
additional information and example.

maxim,boost-mode:
|
|
description:
|
|
In boost mode the device can produce up to 1.2A of total current on both
|
|
outputs. The maximum current on each output is reduced to 625mA then. If
|
|
not enabled explicitly, boost setting defaults to LEDS_BOOST_FIXED in
|
|
case both current sources are used.
|
|
See LEDS_BOOST_* in include/dt-bindings/leds/common.h.
