- Add mdio pins to the cpsw3g pinctrl in u-boot dtsi. It moved to a subnode in the linux dtsi that u-boot doesn't use/support
Unfortunately, this introduces a regression in Linux where the pinctrl node is now affected to both the MAC and PHY, and we end up not being able to probe both.
Uggh!!!! this is the case where u-boot hands over it's device tree to linux kernel to boot, I presume?
Yes, it is :)
I've started to look into making the MAC driver grab the MDIO pinctrl state, but it doesn't look trivial to do since the pinctrl API doesn't support taking an ofnode pointer instead of a device. Shouldn't be too hard either though.
Do you know if there's any other way to fix this?
I dont think there is any other way - I am looping in Ravi who is our networking lead on the topic for ideas.
