wifi: morsemicro: MM81X should be invisible and selected by its users

2026-08-06T12:01:23Z

Morse Micro MM81x wireless devices can have either SDIO or USB interfaces. Hence there is no point in asking the user about these devices when configuring a kernel without MMC or USB support. Fix this by making the core driver symbol invisible, and selecting it by its users when needed.

wifi: mm81x: prevent timers from outliving teardown

2026-07-31T05:42:49Z

The three timer teardown paths call timer_delete_sync_try() and ignore its return value. If a callback is running on another CPU it returns -1 without waiting, and it does not prevent a later rearm even when it does deactivate a pending timer. mm81x_skbq_tx_complete() can rearm the stale-status timer, and the rc and yaps callbacks queue work that rearms their timers. Teardown can therefore continue with a callback still running or the timer rearmed, so it fires after the associated state has been freed. Use timer_shutdown_sync() for these permanent teardowns: it waits for an in-flight callback and prevents any future rearm. In mm81x_rc_deinit() shut the timer down before cancel_work_sync() so the work can no longer recreate the timer/work cycle.

wifi: mm81x: add mm81x Wi-Fi HaLow driver

2026-07-08T02:03:50Z

mm81x is the first Wi-Fi HaLow driver to support the Morse Micro mm81x chip family via USB and SDIO. S1G support in the kernel is only new, and as a result this driver has been scoped to be simple and only support station and AP interface. The Wi-Fi specific features only cover the minimum required for basic use such as powersave, aggregation, rate control and so on. The driver will be extended into the future as S1G support for operations such as ACS, channel switching and so on are added into the wireless stack. The driver has been build tested on a long list of architectures and compilers via Intels LKP. The driver currently supports IEEE80211-2024 US channels only, with AU 2020 also available. In order for this to be expanded additional non-trivial kernel work is required which will begin once the driver is upstream.
