It fixes the issue of Linux booting from the DT embedded by U-boot. The main issue there is that U-Boot doesn't handle the MDIO child node that might have resources attached to it.
Thus, any pinctrl configuration that could be attached to the MDIO child node is effectively ignored. Unfortunately, starting with 6.5-rc1, Linux does just that.
This was solved by duplicating the pinctrl configuration onto the MAC device node. Unfortunately, this doesn't work for Linux since now it has two devices competing for the same pins.
Let me know what you think, Maxime
