From 5571196135abb6d51e01592812997403c136067c Mon Sep 17 00:00:00 2001 From: Esben Haabendal Date: Fri, 6 Apr 2018 14:46:35 +0200 Subject: [PATCH] ARM: dts: ls1021a: Specify TBIPA register address The current (mildly evil) fsl_pq_mdio code uses an undocumented shadow of the TBIPA register on LS1021A, which happens to be read-only. Changing TBI PHY address therefore does not work on LS1021A. The real (and documented) address of the TBIPA registere lies in the eTSEC block and not in MDIO/MII, which is read/write, so using that fixes the problem.
