Another problem here: The code pulses this GPIO low to reset the PHY, so
in other words, the GPIO is active low.

Can you please prepare a separate patch to fix this; you need to change
all existing instances from:

nvidia,phy-reset-gpio = <&gpio 169 0>; /* gpio PV1 */

to:

nvidia,phy-reset-gpio = <&gpio 169 1>; /* gpio PV1, active low */

Insert that new patch before this patch in the series, and then fix this
patch so that any new copies of that property have the correct content
from the start.

Note: I pointed out this problem in my review of V1, but V2 didn't
include a fix for it:-(
