7 title: Maxim MAX77693 MicroUSB and Companion Power Management IC LEDs
10 - Krzysztof Kozlowski <krzysztof.kozlowski@canonical.com>
13 This is a part of device tree bindings for Maxim MAX77693 MicroUSB Integrated
16 There are two LED outputs available - FLED1 and FLED2. Each of them can
17 control a separate LED or they can be connected together to double the
18 maximum current for a single connected LED. One LED is represented by one
21 See also Documentation/devicetree/bindings/mfd/maxim,max77693.yaml for
22 additional information and example.

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