From 455e66bc598935c01621e77709866eb54a6fbd5f Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Thu, 28 Nov 2024 05:11:19 +0100 Subject: [PATCH] arm64: renesas: Disable AVB1 and AVB2 on R8A779G0 V4H White Hawk board The U-Boot is currently not capable of handling ethernet-phy-ieee802.3-c45 PHYs correctly, and also does not handle MDIO bus wide reset-gpios property. Until proper C45 PHY support lands in U-Boot, disable AVB1/AVB2 interfaces. This only disables the two MACs with 88Q2110/88Q2112 100/1000BASE-T1 PHYs on ethenet sub-board, the main board AVB0 ethernet is unaffected.
