[PATCH net-next v4 0/2] airoha: Add the capability to read firmware binary names from dts for Airoha NPU driver

From: Lorenzo Bianconi <lorenzo@kernel.org>
Date: 2026-01-20 10:17:50
Also in: linux-arm-kernel, linux-devicetree, linux-mediatek

This patch is needed because NPU firmware binaries are board specific since
they depend on the MediaTek WiFi chip used on the board (e.g. MT7996 or
MT7992). This is a preliminary patch to enable MT76 NPU offloading if
the Airoha SoC is equipped with MT7996 (Eagle) WiFi chipset.

Changes in v4:
- Add missing MODULE_FIRMWARE definitions for EN7581_7996_FIRMWARE
  binaries
- Link to v3: https://lore.kernel.org/r/20260119-airoha-npu-firmware-name-v3-0-cba88eed96cc@kernel.org (local)

Changes in v3:
- Roll-back to approach proposed in v1 using firmware-name property
- Link to v2: https://lore.kernel.org/r/20260113-airoha-npu-firmware-name-v2-0-28cb3d230206@kernel.org (local)

Changes in v2:
- Introduce "airoha,en7581-npu-7996" compatible string to specify the
  firmware and drop "firmware-name" property
- Link to v1: https://lore.kernel.org/r/20260112-airoha-npu-firmware-name-v1-0-d0b148b6710f@kernel.org (local)
