+title: Maxim MAX77693 MicroUSB and Companion Power Management IC LEDs
+
+maintainers:
+ - Krzysztof Kozlowski <krzk@kernel.org>
+
+description: |
+ 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.
