Description
I'm looking into the driver but could save time if this can be answered by one of the developers:
Does the driver currently support non-standard 5MHz half/quarter-clocking?
Legally this should not pose an issue for 2.4GHz to the best of my knowledge, especially for those with hamradio tickets / IARU licenses.
AFAIK this is present in ath9k (Atheros) but, save some specific RF path quirks in the hardware, it is a strictly driver-related problem and could be ported over to mt76 or any other driver for that matter, unless the firmware actively prevents it. If the driver is fully open source with no blobs no such limitation should exist in practice.
Thank you in advance!

Research direction
The issue names the mt76 driver and ath9k as comparison points, but no source file or test. Start by tracing channel-spacing and half/quarter-clock handling in the driver and any firmware interface; done means confirming whether 5MHz support exists or defining the scope needed to add it.
