The VSC7511, VSC7512, VSC7513 and VSC7514 all have the ability to be controlled either internally by a memory-mapped CPU, or externally via interfaces like SPI and PCIe. The internal CPU of the VSC7511 and 7512 don't have the resources to run Linux, so must be controlled via these external interfaces in a DSA configuration. Add mscc,vsc7512-switch compatible string to indicate that the chips are being controlled externally in a DSA configuration.

Bindings for the Microchip VSC7514 switch driver
|
|
|
|
The VSC7514 switch driver handles up to 11 ports and can inject/extract
|
|
packets using CPU. Additionally, PTP is supported as well as FDMA for faster
|
|
packet extraction/injection.
