[U-Boot] [PATCH v2] dm: usb: fix USB Ethernet without CONFIG_DM_ETH regression

From: Marcel Ziswiler marcel.ziswiler@toradex.com
The following commit enforces CONFIG_DM_ETH for USB Ethernet which breaks any board using CONFIG_USB_HOST_ETHER without CONFIG_DM_ETH which this patch fixes.
commit 69559093f6173dcfcb041df0995063bdbd07d49b dm: usb: Avoid using USB ethernet with CONFIG_DM_USB and no DM_ETH
Tested on Colibri T20/T30 as well as Apalis T30 with CONFIG_USB_HOST_ETHER and CONFIG_USB_ETHER_ASIX enabled and a LevelOne USB-0301 ASIX AX88772 dongle.

Dumb question -- won't it make more sense to add USB_HOST_ETHER Kconfig option and make it depend on CONFIG_DM_USB ?
Best regards, Marek Vasut

I don't think it depends on this. As I understand currently one would be able to run a) USB_HOST_ETHER either without DM_USB at all, b) with just DM_USB (e.g. as currently the case on Colibri T20/T30) or c) later even with DM_ETH which then might depend on DM_USB as well.

OK, I see, makes sense. Thanks for clarifying this chaos :)

What do you think about changing Tegra over to CONFIG_DM_ETH? Do you have any leads on the problem you found?

Sure, once it actually works (;-p).
Right now I would just be happy if it works at all again (e.g. reason for this patch).
Do you have any leads on the problem you found?
No, not yet. Sorry, too many other cans of worms currently (e.g. chasing why upon watchdog reset on T20 one gets stuck in the SPL unfortunately no mainline watchdog driver for T20 yet so using downstream L4T kernel).

Applied to u-boot-dm, thanks!
It turns out I dropped missed applying a patch:
