Sigrok project is dead... There is a single maintainer and he's not willing to merge almost anything, it's been like that for years. I think it's time to fork...
There are a lot of pending changes that I simply cannot review or verify easily since I don't have the hardware the driver is written for. Asking for help has never really been met with much enthusiasm, unfortunately.
Either way, I'll get to these as soon as I can and help is definitely welcome.
