55b858b4e5 [media] cobalt: allow fewer than 8 PCIe lanes
Currently the cobalt driver refuses to load if fewer than 8 PCIe lanes
are assigned. This patch changes this and just issues a warning. The
only time it will refuse to load is if the number of assigned lanes is less
than what the PCIe host is capable of since this suggests that the card
isn't seated correctly in the slot.

b4dbad8fe3 [media] adv7511: log the currently set infoframes
The adv7511 sets up InfoFrames that are used when transmitting video.
Log the contents of those InfoFrames so it is possible to see exactly what
the transmitter is sending.

86bad00a2f [media] cobalt: fix irqs used for the adv7511 transmitter
The interrupt bit assignments use for the adv7511 were off by one.
This means that the current scheme (bit << (4 * stream_index)) can
no longer be used.

Fix this by precalculating and storing the correct masks in the
cobalt_stream struct.

This wasn't noticed before because the adv7511 interrupts are very
rare. But for CEC support these interrupts are essential, so this made
me realize that it wasn't working correctly.

85756a069c [media] cobalt: add new driver
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.
