Mark informative variables with suffix '_inf' to distinguish
them from other non-informative variables with the same name.
If such non-informative varialbes were missed, they are created.

struct otg_fsm may be embedded to device's context structure.
The callbacks may require pointer to struct otg_fsm to obtain
necessary data for its operation (example: regulator reference
for drv_vbus()).

Use the in-kernel pr_debug() calls instead of trying to roll your own
DBG macro. This means the dynamic debugging calls now work here, and
there is no dependency on CONFIG_USB_DEBUG for the phy code anymore.

this will make sure that we have sensible names
for all phy drivers. Current situation was already
quite bad with too generic names being used.
