    + GPIO controller module provides GPIO-s for the SFP slots.
    + It is split into 3 controllers, one output only for the SFP TX disable
    + pins, one input only for the SFP present pins and one input only for
    + the SFP LOS pins.

    + Lattice CPLD onboard the TN48M switches is used for system
    + management.
    +
    + It provides information about the hardware model, revision,
    + PSU status etc.
    +
    + It is also being used as a GPIO expander for the SFP slots and
    + reset controller for the switch MAC-s and other peripherals.
