   12 description:
   13   This module adds support for the RGB LEDs found on the front panel of the
   14   Turris Omnia router. There are 12 RGB LEDs that are controlled by a
   15   microcontroller that communicates via the I2C bus. Each LED is described
   16   as a subnode of this I2C device.

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