AM623: How to modify mdio drive strength

Hello Li,

Our Linux CPSW Ethernet expert is out of office until January 4th. However, your question about modifying mdio drive strength seems to require more of a hardware expert. I'll ask our hardware expert if they have any suggestions. In the meantime, you might find this e2e FAQ as a possible starting point/guide. [FAQ] TDA4VM-Q1: TDA4 Drive Strength Controls - Processors forum - Processors - TI E2E support forums

Best regards,

Hello Li,

Please note that we do not support adjusting drive strength for any of the IOs or peripherals.

Please help me understand the use case.

Have you had a chance to look at the below errata,

The workaround is implemented in SDK  already.

I mean user don't need to care about the errata item, as Linux SDK implemented the workaround.
