| 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. |
