Subject: [PATCH v4 5/6] dt-bindings: leds: Add binding for a multicolor group of LEDs
Date: Fri, 7 Oct 2022 16:56:40 +0200 [thread overview]
Message-ID: <20221007145641.3307075-6-jjhiblot@traphandler.com> (raw)
In-Reply-To: <20221007145641.3307075-1-jjhiblot@traphandler.com>
This allows to group multiple monochromatic LEDs into a multicolor
LED, e.g. RGB LEDs.
