I obviously cannot prove that this will work on all devices, but I have seen several device support PRs for mt7620/mt7621/mt7628 with gpio-keys working (=tested) over the last half year. I intentionally only included mt76xx here, as I have no idea whether this will work on rtxxxx, and if I remember correctly 100 % of them still have gpio-keys-polled set. Best Adrian
