From 7c56408be61ec5597c944bb67c034e7bf01922d5 Mon Sep 17 00:00:00 2001 From: Josef Holzmayr <holzmayr@rsi-elektrotechnik.de> Date: Wed, 2 Oct 2019 21:22:52 +0200 Subject: [PATCH] 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.
