   263	 * @ictx: iommufd file descriptor
   264	 * @dev: Pointer to the parent physical device struct
   265	 * @pasid: the pasid value representing vRID of this virtual device
   266	 * @id: Output ID number to return to userspace for this device
   267	 *
   268	 * The virtual device always tags its DMA with the provided pasid.
   269	 * A successful bind allows the pasid to be used in other iommufd

   271	 * pointer, otherwise returns error pointer.
   272	 *

   274	 * must already claim the DMA ownership over the parent device and
   275	 * the pasid is allocated by the driver itself.

   278	 * has no iommu group associated.
