From ababb5920e8992c9bb7956df3cc85dc68d27dfe8 Mon Sep 17 00:00:00 2001 From: Andre Przywara Date: Mon, 29 Oct 2018 00:56:48 +0000 Subject: sunxi: A64: Re-add syscon to DT node The sun50i-a64.dtsi changes introduced in Linux v4.19-rc1 changed the compatible name for the syscon controller, dropping the generic "syscon" fallback. Using this new DT node will make the Ethernet driver in every older kernel (or non-Linux kernels) fail to initialise the MAC device. To allow booting distribution kernels (from installer images via UEFI, for instance), re-add the syscon compatible string as a fallback. This works with both older and newer kernels.
