David Ellingsworth 4aaec3ea41 V4L/DVB (9034): With the recent patch to v4l2 titled "v4l2: use register_chrdev_region
instead of register_chrdev", the internal reference count is no longer
necessary in order to free the internal stk_webcam struct. This patch
removes the reference counter from the stk_webcam struct and frees the
struct via the video_device release callback. It also fixes an
associated bug in stk_camera_probe which could result from
video_unregister_device being called before video_register_device.
Lastly, it simplifies access to the stk_webcam struct in several
places. This patch should apply cleanly against the "working" branch
of the v4l-dvb git repository.

This patch is identical to the patch I sent a couple of months back
titled "stk-webcam: Fix video_device handling" except that it has been
rebased against current modifications to stk-webcam and it no longer
depends on any other outstanding patches.

Ming Lei a31a405547 V4L/DVB:usbvideo:don't use part of buffer for USB transfer #4
The status[] is part of  uvc_device structure. We can't make sure
the address of status is at a cache-line boundary in all archs,so
status[] might share a cache-line with some fields in uvc_structure.
This can lead to some cache coherence issues(http://lwn.net/Articles/2265/).
Use dynamically allocated buffer instead.

Laurent Pinchart d63beb9ef0 V4L/DVB (9031): uvcvideo: Fix incomplete frame drop when switching to a variable size format.
When streaming in a fixed size format the driver sets a flag in the uvc_queue
structure to drop incomplete incoming frames. The flag wasn't cleared when
switching to a variable size format, which resulted in a broken
'MJPEG after YUV'.

The board init gpio is 0x0, 0x200000 is from previously unloading with

It needs firmware for the tda10046 and analog sound needs saa7134-alsa.

I have support for one more board and need to fix the first revision of
the Asus Tiger DVB-T hybrid. DVB-T currently hangs on the male radio
antenna input, also some small other stuff.

Please report any issues with this patch, the next are depending on this
one.

Darron Broad 34c080295a V4L/DVB (9016): HVR3000/4000 Hauppauge related IR cleanups
From the author:
This patch-set fixes remote control issues I have experienced
with hauppauge drivers in Linux since the PVR-350 and now
with both a NOVA-S+ and HVR-4000. It has also been confirmed
to work with an HVR-1300 user who had exactly the same issue.

Hauppage remote controls use RC5. RC5 has a bit-field which
represents the target device. The hauppauge windows drivers
have a registry key which can enable filtering, but the linux
drivers will accept any target device in this bit field for
internal processing.

This causes problems with setups such as mythtv where remote
control key presses destined for the TV (target = 0) are
interpreted by the kernel and subsequenctly LIRC then mythtv.

Of the remote controls I have to hand (wintv black, pvr/hvr
silver) the hauppauge remotes send one of two device targets
ids, these are interpreted by the patch which then filters
out any non hauppauge addresses.

For demod drivers, we want a single tuning function (set_frontend) to have
access to the properly constructed dvb_frontend_parameters structure, or
the cache values - regardless of whether the legacy or new API is being used.

This cuts down on redundant code in the demod drivers and ensures the
tuning parameters are consistent regardless of the API entry type.

After discussion the following changes were made:
1. Removed the typedefs in frontend.h, use structures.
2. In the frontend.h, remove the 16 command limit on the API and
   switch to a flexible variable length API. For practical reasons
   a #define limits this to 64, this should be discussed.
3. Changed dvb-core ioctl handing to deal with variable sequences
   of commands.

tune-v0.0.3.c is required to use this API, it contains the interface changes.

Steven Toth 13c97bf567 V4L/DVB (8988): S2API: Allow the properties to call legacy ioctls
SET_TONE and SET_VOLTAGE were not previously implemented. Two options
existed. Either cut/paste from the previous ioctl handler into the
process_properties function, which is code duplication. Or, split
the current ioctl handler into it's two major pieces.

Piece 1, responsible for input validation and semaphore acquiring
Piece 2 the processing of the previous ioctls

and finally, a new third pieces where the array of properties
is processed, and can freely call the legacy ioctl handler without
having to re-acquire the fepriv->sem semaphore. This is a clean approach
and ensures the existing legacy ioctls are processed as they were previously
(but with an extra function call) and allows the new API to share code
without duplication.

Steven Toth 6b73eeafbc V4L/DVB (8985): S2API: Added dvb frontend changes to support a newer tuning API
This is an experimental patch to add a new tuning mechanism for
dvb frontends. Rather than passing fixed structures across the
user/kernel boundary, which need to be revised for each new modulation
type (or feature the kernel developers want to add), this implements
a simpler message based approach, allowing fe commands to be broken
down into a series of small fixed size transactions, presented
in an array.

The goal is to avoid changing the user/kernel ABI in the future, by
simply creating new frontend commands (and sequencies of commands) that
help us add support for brand new demodulator, delivery system or
statistics related commmands.

known issues:
checkpatch voilations
feedback from various developers yet to be implemented, relating
to namespace conventions, variable length array passing conventions,
and generally some optimization.

This patch should support all existing tuning mechanisms through the
new API, as well as adding 8PSK, DVB-S2 NBC-QPSK and ISDB-T API support.

For testing and exercise purposes, see the latest tune.c tool
available from http://www.steventoth.net/linux/s2
