Hi all,
This driver is for the Cisco Cobalt card, which is a PCIe device with four
HDMI inputs (adv7604) and optionally one fifth input (adv7842) or one output
(adv7511).
This board is not for sale (sadly) but it is used internally for testing and
prototyping. Many of the HDMI/Digital Video related features that I have added
to V4L2 over the last few years have been prototyped using this driver and I
am planning more new features based on this board.
During the ELC in San Jose a month back I discussed whether it would be OK to
upstream this driver, even though the hardware is not for sale. Mauro had no
problem with this and given the fact that this driver is a good starting
point for similar HDMI hardware, and that this allows me to upstream new
API additions showing them off in this driver (so ensuring that they are
actually used somewhere), I've decided to go ahead with this.
This patch series starts off with a few improvements to other drivers:
The adv7842 now makes the output pixel port format configurable, just like
its cousin adv7604. Note that there is one user of adv7842_platform_data:
arch/blackfin/mach-bf609/boards/ezkit.c. However, this board code has been
broken from the beginning and nobody noticed since gcc doesn't support the
bf609. You need a custom toolchain to compile this :-(
I can't do anything about this, someone (Scott Jiang?) will need to fix
this.
The next patch makes it possible to requeue buffers in vb2 from the driver.
It's a very small change, but the cobalt driver uses that while it is
waiting for a stable video signal.
The next patch is from Jean-Michel Hautbois which hasn't been merged yet
since no driver used that event, but in the next patch I implement it.
The final patch is the cobalt driver itself.
Note that the m00* headers are generated from our FPGA code (slightly
cleaned up by hand), which is why there are many lines > 80 columns.
It makes sense in this case and it does not affect the readability, and
I don't want to edit them too much since that would make it hard to handle
when they are regenerated due to FPGA changes.
And there are also a lot of volatile __iomem pointers: the memory-mapped
registers are written and read directly using struct pointers, so you really
need volatile __iomem there.
In the near future I plan on added CEC support (once the CEC framework has
been merged), colorspace conversion support, possibly deep color support and
more. But let's try to get this driver in first.
Regards,
Hans
