[PATCH net-next v2 0/3] net: ethernet: mtk_eth_soc: improve device tree handling
From: Daniel Golle
Date: Sun Jun 29 2025 - 18:22:04 EST
This series further improves the mtk_eth_soc driver in preparation to
complete upstream support for the MediaTek MT7988 SoC family.
Frank Wunderlich's previous attempt to have the ethernet node included
in mt7988a.dtsi and cover support for MT7988 in the device tree bindings
was criticized for the way mtk_eth_soc references SRAM in device tree[1].
Having a 2nd 'reg' property, like introduced by commit ebb1e4f9cf38
("net: ethernet: mtk_eth_soc: add support for in-SoC SRAM") isn't acceptable
and a dedicated "mmio-sram" node should be used instead.
Support for the hard-coded offset and including the SRAM region as part of
the Ethernet's "reg" MMIO space will still be required in order to support
existing legacy device trees of the MT7981 and MT7986 SoC families.
While at it also replace confusing error messages when using legacy device
trees without "interrupt-names" with a warning informing users that they
are using a legacy device tree.
