- * Driver: dyna_pci10xx
- * Description: Dynalog India PCI DAQ Cards, http://www.dynalogindia.com/
- * Devices: [Dynalog] PCI-1050 (dyna_pci1050)
- * Author: Prashant Shah <pshah.mumbai@gmail.com>
- * Status: Stable

- * Developed at Automation Labs, Chemical Dept., IIT Bombay, India.
- * Prof. Kannan Moudgalya <kannan@iitb.ac.in>
- * http://www.iitb.ac.in
- *
- * Notes :
- * - Dynalog India Pvt. Ltd. does not have a registered PCI Vendor ID and
- * they are using the PLX Technlogies Vendor ID since that is the PCI Chip
- * used in the card.
- * - Dynalog India Pvt. Ltd. has provided the internal register specification
- * for their cards in their manuals.
