I somehow does not like this. If we take this path for any further
properties that we may need, we will end up with a lot of consumer
specific properties stored in a PHY object having their own accessor
functions.
Since this is just an integration detail, what about simply adding this as
a property in device tree node of the OTG controller (and pdata if
considering non-DT support)?
Another option would be some framework for retrieving arbitrary properties
from the PHY, but I'm not really sure there is a need for such.
Best regards,
Tomasz
