Oh and looks like these two phy-twl4030-phy fixes never got
merged from thread "[PATCH 0/2] Two phy-twl4030-usb fixes for
unloading the module":
phy: twl4030-usb: Relase usb phy on unload
phy: twl4030-usb: Fix unbalanced pm_runtime_enable on module reload
I'll resend those. But without those again deeper idle states
are blocked.. And it could be that n900 needs similar additional
patches for it's USB PHY as I've tested things so far only with
phy-twl4030-usb PHY based systems.

Tony
