Just checking.. Do you have CONFIG_OMAP_OCP2SCP=y in your .config? Sounds
like the some transceivers should depend on that for omap4.

Yes, I have OCP2SCP=y.

Hmm well no idea beyond that then. Sounds like Kishon should check it.

The musb-hdrc id is wrong on overo also.

Hmm has there been a fix posted for that?

I couldn't find with a quick look. We debugged and discussed this on an irc
channel with Kishon, who said he'll send a patch. Changing the musb-hdrc ID
on overo fixed the issue, and it looks very similar to the error on 4430sdp.
The overo fix was just:

hmm.. I think using device name to bind the controller and the phy
can no longer be used reliably. I think it's better to have
something like what Grant suggested in my other patch series.. to
have the phy reference into the host controllers platform_data
structure. And for the phy reference I'll have label and id.

Does this makes sense to you?

Sounds OK to me, but I guess that would be for v3.11. I think we
still need a fix for at least overo for v3.10?

Indead, musb-hdrc is broken on overo with 3.10-rc2. The patch posted in this
thread fixes the issue.
