Adding OF binding to genirq.
Version string is setup to the "devicetree".
Compatible string is not setup for now but you can add your
custom compatible string to uio_of_genirq_match structure.
For example with "uio" compatible string:
static const struct of_device_id __devinitconst uio_of_genirq_match[] = {
{ .compatible = "uio", },
{ /* empty for now */ },
};

Perhaps a silly question, but how are you planning on differentiating
between uio_pdrv and uio_pdrv_genirq binding if someone has both enabled?
It is not a silly question. OF support in uio_pdrv_genirq can handle both cases
with/without IRQ (I tested it) and I don't want to add OF support to uio_pdrv.
Not sure if uio_pdrv_genirq without OF can handle UIO without IRQ.
uio_pdrv obviously doesn't have OF bindings at the moment, but it seems
like you could easily parse the memory ranges in addition to the IRQ and
come up with a generic binding that would work for both.
I think the question is if uio_pdrv_genirq can handle both cases, if yes, we can
completely remove uio_pdrv. But it is up to UIO maintainers.
We also have a shiny new Documentation/devicetree these days, so it would
be nice to see the binding documented at the same time.
Sure - make sense.
