From: Hans Verkuil <hans.verkuil@xxxxxxxxx> The cobalt device is a PCIe card with 4 HDMI inputs (adv7604) and a connector that can be used to hook up an adv7511 transmitter or an adv7842 receiver daughterboard. This device is used within Cisco but is sadly not available outside of Cisco. Nevertheless it is a very interesting driver that can serve as an example of how to support HDMI hardware and how to use the popular adv devices.
