| 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. |
