CPSW - acontis/atemsys GitHub Wiki

am335x-icev2

Both ports used by EcMaster

Additionally remove the davinci_mdio node, and add a replacement to the slave sub nodes.

first port used by EcMaster, second port used by patched Linux driver

Just change the slave sub node you want to use. The CPSW Linux driver will start the atemsys driver for the node recursively.
