+title: Ocelot Externally-Controlled Ethernet Switch
+
+maintainers:
+  - Colin Foster <colin.foster@in-advantage.com>
+
+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.
