Well, if hardware doesn't have a TX irq I don't see there's anything we
can do to fix that ;).

Dave, what's your take here? Should we keep a driver from going upstream
just because the hardware is partly broken? I'd really prefer to have an
upstream driver on that SoC rather than some random (eventually even
more broken) downstream code.
