From: David Rivshin Date: Thu, 28 Apr 2016 01:38:26 +0000 (-0400) Subject: drivers: net: cpsw: don't ignore phy-mode if phy-handle is used X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ae092b5bded24d5dc7dae0e0aef4669c169ce874;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git drivers: net: cpsw: don't ignore phy-mode if phy-handle is used The phy-mode emac property was only being processed in the phy_id or fixed-link cases. However if phy-handle was specified instead, an error message would complain about the lack of phy_id or fixed-link, and then jump past the of_get_phy_mode(). This would result in the PHY mode defaulting to MII, regardless of what the devicetree specified.
