There's a ulpi_phy library available in drivers/phy/. Do we want to
use that ?
That also creates a phy-lookup of this PHY so that the ulpi device's
parent
can request the PHY.
I don't have any interest in using those two functions (does two
functions constitute a library?).
Not really.
There's no devm as you say,
I meant to say that you may need to change the existing APIs to the
devm_* APIs.
and it seems to be specific to the ULPI hardware for dwc3 (the only
user) where
the phy is called "usb2-phy".
This was used with TI's USB 2.0 PHY, that has ULPI interface.
This is a phy for the ChipIdea controller
which only has one phy and it's called "usb-phy" in that case.
In a way this is also a USB 2.0 phy, isn't it ?
You may want to modify the APIs available in ulpi_phy library to use
the
devm_* APIs.
The lookup isn't necessary because we use DT to find the lookup. I seem
to recall the phy framework requiring a DT lookup too.
The lookup created in this ulpi_phy.h was used to help getting the PHY
in the
driver for parent device (a core wrapper) of the controller (platform
glue layer) that requests this PHY.
I am not certain at this point about how PHY has to be handled in case
of Chipidea.
Was just throwing in ideas. :-)
Thanks
Vivek
