Log Message:
XU4 GPIO FDT broken snapshot

This is broken. exynos_gpio_bank_config and the call to it are wrong, and
the acquire function doesn't work.

But I'm in over my head and I need to discuss this:

There is a problem with the dtd: it doesn't have addresses for the individual
gpios.  Do I add the addresses to it, or go back to the old version where I
have them hard coded in the driver.

There is a problem with creating the gpio device entries:  I suspect I really
need to treat the pinctrl devices as busses and create the gpios as attached
to those busses, but I'm not familiar with how to do that in NetBSD. At the
minimum, a pointer to a similar situation would give me code to follow.
This is different than the usual bus attachment in that the gpios aren't
devices in the dtd (they don't have "compatible" properties) so they don't
get an attach routine called.  An alternative to generating the bus
attachments might be to add "compatible" properties to the GPIO entries
in the dtd. so that they do get attached in the normal way.

If I'm going to modify the DTD, then it should be checked in, so a decision
on where to check them in would be nice, even if it does mean spreading them
all over because of license issues.  (This DTD is GPL v2)
