To fix this, these PHYs need to be RESET +via a GPIO connected to the PHY's RESET pin. + +Some boards have a single GPIO controlling the PHY RESET pin of all +PHYs on the bus whereas some others have separate GPIOs controlling +individual PHY RESETs. + +In both cases, the RESET de-assertion cannot be done in the PHY driver +as the PHY will not probe till its reset is de-asserted. +So do the RESET de-assertion in the MDIO bus driver. + +[1] - am572x-idk, am571x-idk, a437x-idk + +Signed-off-by: Roger Quadros <rogerq@ti.com> +Signed-off-by: David S.
