+title: Delta Networks TN48M CPLD controller
+
+maintainers:
+ - Robert Marko <robert.marko@sartura.hr>
+
+description: |
+ 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 and reset controller
+ for the switch MAC-s and other peripherals.
