Here is the series to enable RAVB on V3U. I took the DTS patches from the BSP, the rest was developed on mainline tree. Note that only RAVB0 could be tested because the other ones did not have PHYs attached. Also, the last patch is a workaround. 'reset-gpios' cannot be obtained currently which makes the driver fail. The problem is that pinctrl_ready_for_gpio_range() returns EPROBE-DEFER. I hope Geert has an idea because I got lost in the GPIO and V3U pinctrl details there. It seems more of a PFC/CPG/GPIO problem to me. Without the reset-gpio, the driver binds to avb0 and I can ping the host successfully. So, I think at least the first three patches are ready. Let me know your thoughts!
