<p class="Pp">The <code class="Nm">bus_set_pass</code> function is called during
    boot to raise the bus pass level to <var class="Fa">pass</var>. The function
    will rescan the device tree for each pass level between the current pass
    level and the new level that has at least one associated driver. The device
    tree rescans are implemented by invoking the
    <a class="Xr">BUS_NEW_PASS(9)</a> method on the root bus device.</p>
