+
+description: |
+ The Ocelot ethernet switch family contains chips that have an internal CPU
+ (VSC7513, VSC7514) and chips that don't (VSC7511, VSC7512). All switches have
+ the option to be controlled externally, which is the purpose of this driver.
+
+ The switch family is a multi-port networking switch that supports many
+ interfaces. Additionally, the device can perform pin control, MDIO buses, and
+ external GPIO expanders.
