svn commit: r248910 - head/sys/arm/at91

New Revision: 248910
URL: http://svnweb.freebsd.org/changeset/base/248910

Log:
  Change the API for at91_pio_gpio_get() to return the entire masked set
  of bits, not just a 0/1 indicating whether any of the masked bits are on.
  This is compatible with the single in-tree caller of this function right now
  (at91_vbus_poll() in dev/usb/controller/at91dci_atemelarm.c).
