[PATCH net-next] net: mdio: Remove of_phy_attach()

From: Florian Fainelli
Date: Wed Feb 17 2021 - 15:27:19 EST


We have no in-tree users, also update the sfp-phylink.rst documentation
to indicate that phy_attach_direct() is used instead of of_phy_attach().

For the most part, ``flags`` can be zero; these flags are passed to
- the of_phy_attach() inside this function call if a PHY is specified
+ the phy_attach_direct() inside this function call if a PHY is specified
in the DT node ``node``.

``node`` should be the DT node which contains the network phy property,
