From dfea459f20133c89d666f3778e551b50c7e966f0 Mon Sep 17 00:00:00 2001 From: Camelia Groza Date: Thu, 28 Jul 2022 17:28:11 +0300 Subject: board: ls1043ardb: fdt fixups for revision v7.0 boards The LS1043ARDB rev v7.0 board replaces the AQR105 PHY on MAC9 with an AQR113C PHY. The address of the PHY on the MDIO bus changes from 0x1 to 0x8. Enable CONFIG_OF_BOARD_FIXUP and update both u-boot and Linux device trees to reflect this change.
