This will help with the upcoming BCMA -removal from the bgmac driver. Optimally, this should be moved into -phy drivers, but it is too tightly coupled with the bgmac driver to -effectively move it without more changes to the driver. - -Note: the phy_reset was intentionally removed, as the mdio phy subsystem -automatically resets the phy if a reset function pointer is present. In -addition to the moving of the driver, this reset function is added. - -Signed-off-by: Jon Mason -Acked-by: Arnd Bergmann -Reviewed-by: Florian Fainelli -Tested-by: Florian Fainelli -Signed-off-by: David S.
