Subject: [PATCH v2 1/4] dt-bindings: leds: maxim,max77693: convert to dtschema
Date: Tue, 11 Jan 2022 18:50:14 +0100 [thread overview]
Message-ID: <20220111175017.223966-2-krzysztof.kozlowski@canonical.com> (raw)
In-Reply-To: <20220111175017.223966-1-krzysztof.kozlowski@canonical.com>
Convert the LEDs bindings of Maxim MAX77693 MUIC to DT schema format.
The existing bindings were defined in ../bindings/mfd/max77693.txt.

+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.

+ case both current sources are used.
