The initial soc-camera scaling and cropping implementation turned out to be
incompliant with the V4L2 API, e.g., it expected the user to specify cropping
in output window pixels, instead of input window pixels. This patch converts
the soc-camera core and all drivers to comply with the standard.

Use host-side image scaling when the client fails to set the requested format.
We also have to take scaling into account when performing host-side cropping.
Similar to cropping we try to use client-side scaling as much as possible to
preserve bus bandwidth and optimise the frame-rate.

Prohibit S_FMT and S_CROP with a different window width or height after video
buffer initialisation. This simplifies the work to be done in specific host and
client drivers, and it doesn't seem to make much sense to allow these changes.
We do however allow S_CROP with equal width and height to just move the window,
this doesn't affect video buffer management and is usually easy enough to
implement.

Not all video capture devices can configure arbitrary cropping, whereas the
CEU module on SuperH CPUs can crop with pixel precision. However, we want to
use camera cropping if possible to save bandwidth and increase the frame-rate.
This patch verifies whether the camera managed to crop exactly the requested
rectangle, and if not, uses host-side cropping. To be able to crop on CEU we
have to preserve camera rectangle too, for which the host_priv member in
struct soc_camera_device is used. We now allocate memory dynamically, thus we
have to use the .put_formats() method from struct soc_camera_host_ops to free
it.

Patch
[PATCH] video: use videobuf_waiton() in sh_mobile_ceu free_buffer()
was not quite correct. It closed a race, but introduced a potential
lock-up, if for some reason an interrupt does not come. This has been
observed in tests with tw9910. This patch safely dequeues buffers without
waiting for their completion. It also moves a buffer state assignment
under a spinlock to make it atomic with queuing of the buffer.

Convert the soc-camera framework to use the v4l2-(sub)dev API. Start using
v4l2-subdev operations. Only a part of the interface between the
soc_camera core, soc_camera host drivers on one side and soc_camera device
drivers on the other side is replaced so far. The rest of the interface
will be replaced in incremental steps, and will require extensions and,

From: Henrik Kurelid <henke@kurelid.se>
The AVC protocol uses the same command for tuning and PID filtering and
since dvb-core uses a software zigzagging to do automatic retuning this
could cause all PID filters to be cleared. PID filter information is
now included in all DSD commands to the card.
Background:
There is a problem in the firedtv driver that causes recordings to stop
if the SW zigzag algorithm in dvb-core kicks in with a retune after the
application has set up the PID filters. Since tuning and setting PID
filters uses the same AVC command (DSD) and only the replace subfunction
is supported by the card, it is not possible to do a retune without
setting the PID filters. This means that the PID filtering has to be
sent in each tune.
This problem applies to C and T cards since S and S2 cards tune using a
vendor specific command. The patch corrects the problem by sending the
PID list in each tune. I have tested it on my T card with a good
result.
How to trigger problem: Zap to a channel and output AV to a file, e.g.
"tzap -c channels.conf SVT1 -r -o SVT1.ts". After a short while, pull
the antenna cable from the card. The lock on the channel will disappear
and the TS file will stop increasing in size. Wait a couple of seconds.
Replug the cable again. You will get a lock on the channel again, but
the TS file will never increase in size agains sinze no PIDS are
filtered.
Tested with kaffeine with DVB-T and DVB-C: Fixes retuning after antenna
was plugged out and back in with DVB-T. Does not fix this with DVB-C,
but also doesn't regress on DVB-C.

Attached is a patch which fixes tuning to low frequency channels with
stb0899+tda8261 cards like the KNC TV-Station DVB-S2.
The cause of the issue was a broken if construct, which should have been
an if/else if, so that the setting for the lowest matching frequency is
applied.
Without this patch for example tuning to "arte" on Astra 19.2, 10744MHz
SR22000 failed most times and when it failed the communication between
driver and tda8261 was completely broken.
This problem disappears with the attached patch.

Now that we've figured out the higher compression settings (supported in
libv4l-0.6.0 and later, so after this patch the driver should be used with
libv4l-0.6.0 or higher only!), we can enable higher framerates. Which
means lower exposure times, which is important for the use of the pac207
in full daylight.
This patch also tweakes the brightness default and the per color gain
balances to use the values which are adviced by Pixart in the pac207
application note.
