    +description:
    + This module adds support for the RGB LEDs found on the front panel of the
    + Turris 1.x routers. There are 8 RGB LEDs that are controlled by CZ.NIC CPLD
    + firmware running on Lattice FPGA. Firmware is open source and available at
    + https://gitlab.nic.cz/turris/hw/turris_cpld/-/blob/master/CZ_NIC_Router_CPLD.v
