Just looking at this code in mainline, and I don't trust my
understanding quite enough to send a patch myself, but doesn't this want
to be pdev->tph_req_type, rather than tph_mode?

Yeah, you are right - this is supposed to be pdev->tph_req_type instead of tph_mode. We disable TPH first by clearing (zero) the "TPH Requester Enable" field and needs to set it back using tph_req_type.

Do you want to send in a fix? I can ACK it. Thanks for spotting it.
