New Revision: 279620
URL: https://svnweb.freebsd.org/changeset/base/279620
Log:
Add a bus_probe_nomatch() method for gpiobus/ofw_gpiobus.
This prints a warning when your system have a hinted child or a FDT child
node for which you don't have a matching driver:
gpiobus0: <unknown device> at pin(s) 24 irq 24
