+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 for the SFP slots.

+ compatible:
+ const: delta,tn48m-cpld

+ I2C device address.
+ maxItems: 1
+
+ gpio-controller: true
+
+ "#gpio-cells":
+ const: 2
+ description:
+ The first cell is the pin number and the second cell is used to specify
+ the gpio active state.
+
+required:
+ - compatible
