Hi,

Adding Rob and HNS to Cc too for commit cf081d009c44 ("usb: musb: Set the
DT node on the child device").

To me it seems that we now somehow have a probe issue for musb depending
on how it gets probed depending on the following line:

device_set_of_node_from_dev(&musb->dev, &pdev->dev);

I think commit 239071064732 ("partially Revert "usb: musb: Set the DT node
on the child device"") fixed the issue for omap3 that still uses hwmod
by removing the device_set_of_node_from_dev(). However, it somehow broke
SoCs using ti-sysc like omap4.

My guess is commit 239071064732 will fix the issue for you?

I'm not sure what the proper fix here might be to have both working
though :)

FYI, I have a pending patch set to convert omap3 also to probe with
ti-sysc for musb, but seems like there's some other issue here that
should be fixed first.

Regards,

Tony
