wifi: mt76: relicense to BSD-3-Clause-Clear

2025-11-24T13:37:54Z

MediaTek has asked to switch from the ISC license to BSD-3-Clause-Clear, in order to improve clarity and the legal integrity of the code. The BSD-3-Clause license includes the "no endorsement" clause, which is important for protecting the reputation of the original authors and contributors by preventing unauthorized use of their names for endorsement purposes. This clause is absent in the BSD-2-Clause license, which is more permissive but lacks this specific protection. This change also cleans up the license of some Kconfig/Makefile files, which were accidentally marked as GPL. The GPL 2.0 remains in use on mt76x0, as well as two source files in mt7615 for which the license situation still needs to be clarified.

wifi: mt76: mt7915: add bf backoff limit table support

2025-11-24T13:37:53Z

The commit 22b980badc0f ("mt76: add functions for parsing rate power limits from DT") introduced generic support for rates limits in the devicetree. But the mt7915 supports beamforming and has another table for configuring the backoff limits. These can be configured in the DT with the paths-* properties. The path-*-bf are the ones relevant for beamforming and the ones without -bf suffix for "traditional" path backoff.

wifi: mt76: un-embedd netdev from mt76_dev

2024-06-21T02:30:00Z

Embedding net_device into structures prohibits the usage of flexible arrays in the net_device structure. For more details, see the discussion at [1]. Un-embed the net_devices from struct mt76_dev by converting them into pointers, and allocating them dynamically. Use the leverage alloc_netdev_dummy() to allocate the net_device object at mt76_dma_init(). The free of the device occurs at mt76_dma_cleanup().

wifi: mt76: Drop unnecessary error check for debugfs_create_dir()

2023-09-30T18:03:05Z

debugfs_create_dir() returns ERR_PTR and never return NULL. As Russell suggested, this patch removes the error checking for debugfs_create_dir(). This is because the DebugFS kernel API is developed in a way that the caller can safely ignore the errors that occur during the creation of DebugFS nodes. The debugfs APIs have a IS_ERR() judge in start_creating() which can handle it gracefully. So these checks are unnecessary.

mt76: remove variable set but not used

2021-12-13T14:56:03Z

The code that uses variable queued has been removed, and "mt76_is_usb(dev) ? q->ndesc - q->queued : q->queued" didn't do anything, so all they should be removed as well.
