Subject: [PATCH net-next RFC 2/2] net: ethernet: pch_gbe: Convert to mdiobus and phylib
Convert this driver to use the mdio bus and phylib infrastructure. It
will then use the common AT803X PHY driver, rather than use its own
code. Have the shared code also handle the GPIO used to reset the PHY.
To implement disabling PHY hibernation, which appears to cause issues
on the minnow board, add a PHY fixup.
Over all, these changes should make it easier to use other PHYs with
the MAC chip, and reduces the lines of code.
Signed-off-by: Andrew Lunn <andrew@...n.ch>
