Looks like we've got a party :) A.T. It looks like you have all the basic elements of a driver, and use dma buffering which is cool.
I submitted this pull request https://github.com/sigrokproject/libsigrok/pull/181 for my version. I added 3 analog channels and up to 21 logic channels as well as SW triggering and run length encoding. There is also https://github.com/markb139/pico_logic with driver https://github.com/markb139/libsigrok. markb139's implementation is interesting because it uses a real USB TMC implementation rather than serial CDC (I'm really interested to know if that provides noticeable bandwidth improvements). At this point markb139 hasn't submitted an official pull request, waiting at least in part to figure out USB ID issues. Note: I'm not a moderator/curator or approver for the sigrok repos, and I have not had any contact from the developer as to which of any (or a merge or ???) might be pulled into the official sigrok repo.
