[PATCH v8 02/16] dt-bindings: net: mediatek,net: allow up to 8 IRQs

From: Frank Wunderlich <hidden>
Date: 2025-07-06 13:22:36
Also in: linux-arm-kernel, linux-devicetree, linux-mediatek, linux-pm, lkml
Subsystem: networking drivers, open firmware and flattened device tree bindings, the rest · Maintainers: Andrew Lunn, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Torvalds

From: Frank Wunderlich <redacted>

Increase the maximum IRQ count to 8 (4 FE + 4 RSS/LRO).

Frame-engine-IRQs (max 4):
MT7621, MT7628: 1 IRQ
MT7622, MT7623: 3 IRQs (only two used by the driver for now)
MT7981, MT7986, MT7988: 4 IRQs (only two used by the driver for now)

Mediatek Filogic SoCs (mt798x) have 4 additional IRQs for RSS and/or
LRO.
