AM2432: How to create custom Ethernet PHY driver

Hi Expert,

In SDK, I can see that DP83869HM is used for EVM. In our product, LAN8740A will be used for MII and 3rd party Ethernet/IP.

Could you give me a guide on how to implement this PHY driver for LAN8740A? I could refer to TI documents below,

https://software-dl.ti.com/mcu-plus-sdk/esd/AM243X/08_02_00_12/exports/docs/api_guide_am243x/BOARD_ETHPHY_PAGE.html#autotoc_md640

Is this the correct starting point? or Is there any other information you can guide?

And as a first step, I need to estimate the effort, like whether or not it is a simple change or not.

I would appreciate it if you share your experience and knowledge about the required effort/steps as well.

Regards,

Moonil
