This also fixes a bogus error > message that would be emitted. > > Patch 4 fixes makes the binding documentation more explicit that > exactly one PHY property should be used, and also marks phy_id as > deprecated. > > Patch 5 cleans up the fixed-link case to work like the now-fixed > phy-handle case. > > I have tested on the following hardware configurations: > - (EVMSK) dual emac, phy_id property in both slaves > - (EVMSK) dual emac, phy-handle property in both slaves > - (EVMSK) a bad phy-handle property pointing to &mmc1 > - (EVMSK) phy_id property with incorrect PHY address > - (BeagleBoneBlack) single emac, phy_id property > - (custom) single emac, fixed-link subnode > > Andrew Goodbody reported testing v2 on a board that doesn't use > dual_emac mode, but with 2 PHYs using phy-handle properties [1]. > > Nicolas Chauvet reported testing v2 on an HP t410 (dm8148). > > Markus Brunner reported testing v1 on the following [2]: > - emac0 with phy_id and emac1 with fixed phy > - emac0 with phy-handle and emac1 with fixed phy > - emac0 with fixed phy and emac1 with fixed phy Quickly boot tested these against next on dra62x-j5eco EVM: Tested-by: Tony Lindgren
