No, I'm currently spending almost 100% of my GPIO time on getting the
libgpiod DBus API ready and I should send the first version by the end
of this week. After that I'll be at EOSS and then on vacation, so the
earliest I will get to working on it is early May.

If you feel like giving it another shot - go for it. I believe the
device link problem I described previously[1] must be fixed first. I
would also consider a more generic solution in the interrupt subsystem
that would make it aware that interrupt controllers may be torn down
with interrupts still requested.

As I said: I will get to it but not in the following couple weeks.
