Subject: [PATCH 081/203] net: phy: call mdiobus_scan() after adding a fixed
|
|
PHY
|
|
|
|
The fixed_phy_add() function allows to register a fixed PHY. However,
|
|
when this function gets called *after* fixed_mdio_bus_init() (which
|
|
gets called at the module_init stage), then the fixed PHY is not
|
|
registered into the phylib.
|
|
|
|
In order to address this, we add a call to mdiobus_scan() in
|
|
fixed_phy_add() to ensure that the PHY indeed gets registered into the
|
|
phylib, even if the fixed_phy_add() is called after
|
|
fixed_mdio_bus_init().
|
|
|
|
This is needed because until now, the only code that was calling the
|
|
fixed_add_phy() function was PowerPC-specific platform code, which
|
|
could ensure that such fixed PHYs get registered before
|
|
fixed_mdio_bus_init() is called.
|
|
|
|
However, with the new of_phy_register_fixed_link() function, device
|
|
drivers can parse their 'fixed-link' property and register a fixed PHY
|
|
at ->probe() time, which may happen after fixed_mdio_bus_init() is
|
|
called.
