There are 12 RGB LEDs that are controlled by a microcontroller that communicates via the I2C bus. Each LED is described as a subnode of this I2C device. properties: compatible: const: cznic,turris-omnia-leds reg: description: I2C slave address of the microcontroller. maxItems: 1 "#address-cells": const: 1 "#size-cells": const: 0 patternProperties: "^multi-led@[0-9a-b]$": type: object $ref: leds-class-multicolor.yaml# unevaluatedProperties: false description: This node represents one of the RGB LED devices on Turris Omnia.
