Dear TI,

  we want to use mcu_cpsw, and connect DP83867 INT/PWDN to MCU_RGMII1_INT, how to config DP83867 in dts and code?

  our SDK version is 8.06, please help.

    Dear TI，

      after check with hardware, we change DP83867 PWDN/MCU_RGMII1_INT from WKUP_GPIO0_55 to WKUP_GPIO0_10, how to config DP83867 in dts and code?

      please help.

    TI is not handling the INT/PWDN signal of PHY connected to WKUP_GPIO0_55. Might be connected for future use case of PWDN to keep PHY In low power mode.

    This is the reason you could not find any details related to that WKUP_GPIO0_55 in dts and code.

    No need to worry about the change of INT pin to different GPIO. just make sure the GPIO (WKUP_GPIO0_10) you are using will not be used for other purpose.
