> From: Ye Li <[email protected]> > For dual ethernet controllers, the HW design may connect ETH phys to > one MDIO ports. So two different ethernet drivers have to share MDIO bus. > Since two ethernet drivers are independent, we can't ensure their probe > order. > To resolve this problem, introduce an eth phy generic driver and uclass. > After eth-uclass binds, we search the mdio node and binds the phy node > with the eth-phy-generic driver. > When one eth driver get its phy device, the parent of phy device will > probe prior than phy device. So this ensure the eth driver ownes the > MDIO bus will be probed before using its MDIO. > Signed-off-by: Ye Li <[email protected]> > Signed-off-by: Peng Fan <[email protected]> Applied to u-boot-imx, master, thanks !
