I've been working on an hsic driver for apq8074 which matches the same
hardware. I was going to send it out this week but got dragged down into
the HS phy part of it and fixing all the OTG handling. I'd prefer we
don't go down the route of your patches which ioremap the controller
address space in the phy driver. Instead we should use the ULPI bus that
was recently introduced. Care to take my patches for a spin[1]? I'll Cc
you on them once I send them out, which should be very soon.

Hi Stephen,

No problem, my implementation was very basic and Host-mode only.

I must check if it's still functional but yes, I'll take your patches.
