18b5dc2ed7 V4L/DVB (9721): cx18: Change to singlethreaded global work queue thread for deferable work
Change to singlethreaded global work queue thread for deferable work,
instead of the kernel default multithreaded work queue.  This ensures
execution of deferable work is always in the proper order, so caputred buffers
don't get reordered.

ee2d64f5cc V4L/DVB (9720): cx18: Major rewrite of interrupt handling for incoming mailbox processing
A major rewrite of interrupt handling for incoming mailbox processing, to split
the timing critical steps from the the deferrable steps as the sending XPU on
the CX23418 will time out and overwrite our incoming mailboxes rather quickly.
Setup a pool of work "order forms" for the irq handler to send jobs to the new
work handler routine which uses the kernel default work queue to do the
deferrable work.  Started optimizing some of the cx18-io calls as they are now
the low hanging fruit for recoving microseconds back from the timeline.
Future optimizations will get rid of mmio read retries, mmio stats logging, and
combine smaller functions in the irq path into the larger ones to save ~2 us
each.

d20ceecd0c V4L/DVB (9598): cx18: Prevent CX23418 from clearing it's outgoing ack interrupts to driver
When the CX23418 CPU unit sent out an ack interrupt to the linux driver, it
also received that interrupt and cleared the flag before the linux driver could
see what the interrupt was for.  This fix prevents the CPU from receiving an
IRQ for it's own outgoing ack's to the linux driver.  This fix is critical now
that the linux driver doesn't poll but relies on these ack interrupts.

cx18: Improve handling of outgoing mailboxes detected to be busy.  When
encountering a busy mailbox, sleep instead of polling, and wait for interrupt or

make sure we never create a situation where we mark the mailbox busy upon

mailbox.

cx18: Reduce number of mmio read retries to improve performance.  Experiments
have shown 2 things: read retries never improve the result of a suspect mmio
read from the CX23418 (the result stays all 0xff's), and that most of the
suspected read failures are actually proper reads of values that should be
all 0xff's.  This change reduces the number of read retries and keeps the
count separate from write retries.

* At High Symbol Rates we do not have enouph machine cycles to handle the

* Most of the equations have been calculated for a master clock of 99 MHz,

a2070c6654 V4L/DVB (9747): em28xx: Properly handles XCLK and I2C speed
The previous patches removed XCLK and I2C magic. Now, we finally know
what those registers do. Also, only a very few cards need different
setups for those.

Instead of keeping the setups for those values inside the per-device
hack magic switch, move the uncommon values to the board-specific
struct, and have a common setup for all other boards.

So, almost 100 lines of hacking magic were removed.

A co-lateral effect of this patch is that it also fixes a bug at em28xx-core, where xclk
were set, without taking any care about not overriding a previous xclk setup.

2ea487e2d0 V4L/DVB (9698): Add another vflip quirk for the s5k4aa
The msi gx7xx range of computers seem to be a strange lot with lots of different sys vendor names and differently oriented sensors. This commit adds another quirk for a range of them.

Currently the spca501 driver only works the first time used, then the cam needs
to be unplugged or the driver reloaded, this is because currently the data
which should be send each time the stream is started is send only once.
Likewise currently the data to initialize the cam is send from the probe
function, and thus will not get send after a suspend/resume.
This patch fixes this by sending both at the right time.

23867b2511 V4L/DVB (9661): uvcvideo: Commit streaming parameters when enabling the video stream
Sonix-based cameras seem to require the host to commit video streaming
parameters before selecting the alternate endpoint. While most applications
issue a VIDIOC_S_FMT ioctl before starting streaming, this is not required
by the V4L2 specification.

The problem has been noticed on Ubuntu 8.10 with applications using libv4l.
The library blocks VIDIOC_S_FMT calls when the requested format is identical
to the currently selected format. As the driver commits video streaming
parameters when initialising the device, only the first run of a
libv4l-enabled application would succeed.

For the sake of completeness, experiment showed that the camera keeps sending
12 bytes isochronous packets (header only, no data) without toggling the FID
bit if video streaming parameters haven't been committed before selecting the
alternate endpoint.

instead of making sure that the volumes were set on mute state.

This patch improves support for ac97 devices by allowing to use any
inputs, and making sure that unused inputs are set on mute state.

Yet, some work is still needed to select the AC97 output.
