X-Git-Tag: v2020.10~454^2~35
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=7c56408be61ec5597c944bb67c034e7bf01922d5;p=platform%2Fkernel%2Fu-boot.git

net: macb: let miiphy_read/_write pass arbitrary addresses

This allows passing arbitrary addresses through macb_miiphy_read and
macb_miiphy_write, therefore enabling the mii command to access
all mdio bus devices instead of only the defined phy.
