Sorry for the late reply. I just sent a v2 adding
mdiodev_get/set_drvdata helpers
and using them in gmii2rgmii driver.
I did not add a corresponding phydev helper because there is no "struct dev" in
"struct phy_device" and I dint know if there were any users to add the member
and then a helper for driver data. Also,
strutct phy_device { struct mdio_device { struct device }}
is already available and it seemed logical to use that field to
set/get driver data
for gmii2rgmii. Please let me know if v2 is okay.

Regards,
Harini
