Hello,

This patch is a proposal to support the register/unregister/register
sequence on a given mdio bus.

I forgot to ask, if this limitation was made on purpose ?
In other terms: no one should ever try to register, unregister and register again
a given mii_bus structure.


I use the register/unregister/register sequence to add a fallback when the
of_mdiobus_register (this function calls mdiobus_register with phy_mask
set to ~0) does not register any phy device (because the device tree does
not define any phy).
In this case I call mdiobus_unregister and then call mdiobus_register with
a phy_mask set to 0 to trigger a full mdio bus scan.

I'm not sure this is the right way to do it (this is why I added RFC in the
subject).

Could someone help me figuring out what I should use to implement my fallback ?

1) use the register/unregister/register sequence
2) reimplement the "for (i = 0; i < PHY_MAX_ADDR; i++)" mdiobus_scan loop

Thanks.

Best Regards,
Boris
