From 73d527aef68f7644e59f22ce7f9ac75e7b533aea Mon Sep 17 00:00:00 2001 From: Madalin Bucur Date: Wed, 22 Jan 2020 15:20:28 +0200 Subject: powerpc/fsl/dts: add fsl,erratum-a011043 Add fsl,erratum-a011043 to internal MDIO buses. Software may get false read error when reading internal PCS registers through MDIO. As a workaround, all internal MDIO accesses should ignore the MDIO_CFG[MDIO_RD_ER] bit.
