New Revision: 355598
URL: https://svnweb.freebsd.org/changeset/base/355598
Log:
Do not attach children of owc_gpiobus until interrupts are working.
The children of the bus need to do IO on the bus to probe for hardware
presence. Doing IO means timing the bus states using sbinuptime(), and
that requires working timecounters, which are not initialized until after
device attachment has completed.
