10 - Krzysztof Kozlowski <krzk@kernel.org>
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

14 LED and flash LED devices provide the same basic functionality as current
15 regulators, but extended with LED and flash LED specific features like
18 Many LED devices expose more than one current output that can be connected
19 to one or more discrete LED component. Since the arrangement of connections
20 can influence the way of the LED device initialization, the LED components
