DP83822H: Enable support for DP83822 Eth PHY in U-boot

Part Number: DP83822H

Hi Team,

I'm trying to enable support for TI DP83822 ethernet PHY in u-Boot, but I'm unable to find the official Device tree binding document for this Eth PHY.
Would be a great help if you can share the steps/documents to enable DP83822 Eth PHY in u-boot.

Please do share the reference/sample DT code if you have one.

    Hi Avinash,

    Let me check with my team internally, and I will get back to you tomorrow with a response on whether we support DP83822 in u-boot.

    Regards,

    Hi Avinash,

    There is no device tree binding for the DP83822 in u-boot. The DP83822 u-boot implementation uses the generic PHY u-boot framework and just registers the PHY's uid and name. The callbacks are to the genphy_* basic calls. You need to enable CONIFG_PHY_TI_GENERIC in your config file to register the name. Otherwise, the PHY will come up as Generic by name.
