description:
  This module adds support for the RGB LEDs found on the front panel of the
  Turris Omnia router. 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.

    description:
      This node represents one of the RGB LED devices on Turris Omnia.
      No subnodes need to be added for subchannels since this controller only
      supports RGB LEDs.
