From a4f63342d03d2dfb61d9e52f30d084d0780aaddd Mon Sep 17 00:00:00 2001 From: Martin Blumenstingl Date: Sat, 20 Jun 2020 21:26:41 +0200 Subject: [PATCH] net: stmmac: dwmac-meson8b: add a compatible string for G12A SoCs Amlogic Meson G12A, G12B and SM1 have the same (at least as far as we know at the time of writing) PRG_ETHERNET glue register implementation. This implementation however is slightly different from AXG as it now has an undocument "auto cali idx val" register in PRG_ETH1[17:16] which seems to be related to RGMII Ethernet. Add a new compatible string for G12A SoCs so the logic for this new register can be implemented in the future. Signed-off-by: Martin Blumenstingl Signed-off-by: David S.
