[PATCH v2 0/3] net: ti: am65-cpsw-nuss: Fix DT binding handling of pinctrl

[Maxime Ripard]

Hi,

This series is based on:
https://lore.kernel.org/all/20230713072019.3153871-1-nm@ti.com/
https://lore.kernel.org/all/20230720215935.107398-1-rogerq@kernel.org/

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
