This is a big patch, yet trivial: now that all tuners use the DVBv5
way to pass parameters (e. g. via fe->dtv_property_cache), the
extra parameter can be removed from set_params() call.
After this change, very few DVBv3 specific stuff are left at the
tuners.

dvb_register calls videobuf_dvb_register_bus, but if that returns
a failure the module will be unloaded without clearing the
value of core->gate_ctrl which will cause an oops in macros
called from video_open in cx88-video.c

All the modified drivers didn't have any version increment since
Jan, 1 2011. Several of them didn't have any version increment
for a long time, even having new features and important bug fixes
happening.
As we're now filling the QUERYCAP version with the current Kernel
Release, we don't need to maintain a per-driver version control
anymore. So, let's just use the default.
In order to preserve the Kernel module version history, a
KERNEL_VERSION() macro were added to all modified drivers, and
the extraver number were incremented.
I opted to preserve the per-driver version control to a few
pwc, pvrusb2, s2255, s5p-fimc and sh_vou.
A few drivers are still using the legacy way to handle ioctl's.
So, we can't do such change on them, otherwise, they'll break.
Those are: uvc, et61x251 and sn9c102.
The rationale is that the per-driver version control seems to be
actively maintained on those.
Yet, I think that the better for them would be to just use the
default version numbering, instead of doing that by themselves.
While here, removed a few uneeded include linux/version.h

The BKL conversion of this driver seems to have gone wrong.
Loading the cx88-blackbird driver deadlocks.
The cause: mpeg_ops::open in the cx2388x blackbird driver acquires the
device lock and calls the sub-driver's request_acquire, which tries to
acquire the lock again. Fix it by clarifying the semantics of
request_acquire, request_release, advise_acquire, and advise_release:
now all will rely on the caller to acquire the device lock.

The BKL conversion of this driver seems to have gone wrong. Various
uses of the sub-device and driver lists appear to be subject to race
conditions.
In particular, some functions access drvlist without a relevant lock
held, which will race against removal of drivers. Let's start with
that --- clean up by consistently protecting dev->drvlist with
dev->core->lock, noting driver functions that require the device lock
to be held or not to be held.
After this patch, there are still some races --- e.g.,
cx8802_blackbird_remove can run between the time the blackbird driver
is acquired and the time it is used in mpeg_release, and there's a
similar race in cx88_dvb_bus_ctrl. Later patches will address the
remaining known races and the deadlock noticed by Andi. This patch
just makes the semantics clearer in preparation for those later
changes.

A Hauppauge HVR 4000 is used on a School On Internet Asia (SOI Asia)
project in order to carry IP traffic over ULE. However, there is an
issue with high latency jitter.
My boss, Husni, identified the problem and provided a patch for it.
The default buffer size of 32 TS frames on cx88 causes the high latency,
so our deployment changes that to 6 TS frames. This patch made the
buffer size tunable, while keeping the default buffer size of 32 TS
frames unchanged.

Upcoming I2C v4l2_subdev drivers need a way to control the subdevice
power state from the core. This use case is already partially covered by
the tuner s_standby operation, but no way to explicitly come back from
the standby state is available.
Rename the tuner s_standby operation to core s_power, and fix tuner
drivers accordingly. The tuner core will call s_power(0) instead of
s_standby(). No explicit call to s_power(1) is required for tuners as
they are supposed to wake up from standby automatically.

It enables autodetection of card, sound in analog TV , sound in FM radio

doesn't work, I don't even know how it works. Some guys wrote me that FM
radio works with TV tuner used instead of radio part (symlink video0 ->

As Randy Dunlap <randy.dunlap@oracle.com> reported, cx88 has some compilation issues:
drivers/built-in.o: In function `cx88_call_i2c_clients':
(.text+0x20af17): undefined reference to `videobuf_dvb_get_frontend'
drivers/built-in.o: In function `cx8802_probe':
cx88-mpeg.c:(.devinit.text+0x268c4): undefined reference to `videobuf_dvb_alloc_frontend'
cx88-mpeg.c:(.devinit.text+0x268ea): undefined reference to `videobuf_dvb_dealloc_frontends'
With those configs:
CONFIG_VIDEO_CX88=y
CONFIG_VIDEO_CX88_BLACKBIRD=y
CONFIG_VIDEO_CX88_DVB=m
CONFIG_DVB_CORE=m
After carefully examining the code, with the current code, several cx88 drivers
(cx8800, cx8802, cx88_dvb and cx88_blackbird) should be compiled as a module,
if one of them is marked as such. Just fixing Kconfig could create a very complex
set of rules. Also, this hides a problem with the current approach where the dvb
functionality weren't confined inside dvb module.
What happens is that:
- cx88-i2c (part of cx8800) has some special rules if DVB;
- cx88-mpeg (cx8802 module) has also part of DVB init code;
- cx88-dvb has the rest of the dvb code;
- cx88-blackbird can be used with cx88-mpeg, having cx88-dvb or not.
So, instead of doing some tricks at Kconfig and wait for a next breakage,
this patch moves the dvb code inside cx88-i2c and cx88-mpeg into cx88-dvb.
Another problem is that cx8802 were being compiled, even without cx88-dvb
and cx88-blackbird modules.
While on this code, let's fix also a reported problem:
http://www.linuxtv.org/pipermail/linux-dvb/2009-January/031225.html
A solution for the issue were proposed here:

There already is an report at kernel bugzilla about this issue:
http://bugzilla.kernel.org/show_bug.cgi?id=9455
When enabling extra checks for the i2c-bus of cx88 based cards by
loading i2c_algo_bit with bit_test=1 this may trigger an oops
when loading cx88_dvb.
This is caused by the extra check code that detects that the
sda-line is stuck high and thus does not register the i2c-bus.
cx88-dvb however does not check if the i2c-bus is valid and just
uses core->i2c_adap to attach dvb frontend modules.
This leads to an oops at the first call to i2c_transfer:

This add frontend R/W mutual exclusion.
Prior to this point in time it was possible to open both
frontends simultaneously which an MFE card cannot support.
In order to stop this, a delayed open is performed which
has the following function:
- Return EBUSY after a configurable amount of time
if a frontend is unavailable due to the other being
in use.
- Only allow opening of a frontend if the kernel thread
of the other has stopped.
This solution was chosen to allow switching between
frontends to work as seamlessly as possible. When both
frontends are actually opened simultaneously then one
will only open, but if quick switching is performed
between one of many then the new open will succeed in
a clean fashion rather than interrupting a kernel
thread.

This adds a configurable (one per card) gate control option
for multi-frontend. Prior to this point gate control was
assumed to be on the primary frontend, this is a fault
when the gate to the analogue section is on the secondary
which is the default for both the HVR-3000 and HVR-4000
in MFE.

A number of reference to videobuf_dvb_get_frontend used an invalid
index. This has been fixed.
The section for the HVR3000 in advise_acquire was redundant as
the same logic is used on the HVR4000. This has been removed
and both cards now use the same function.
A number of small errors and whitespace errors are also fixed.

A detailed description from the original patches 2 years ago:
"The WinTV-HVR3000 has a single transport bus which is shared between
a DVB-T and DVB-S modulator. These patches build on the bus acquisition
cx88 work from a few weeks ago to add support for this.
So to applications the HVR3000 looks like this:
/dev/dvb/adapter0/fe0 (cx24123 DVB-S demod)
/dev/dvb/adapter0/fe1 (cx22702 DVB-T demod)
Additional boards continue as before, eg:
/dev/dvb/adapter1/fe0 (lgdt3302 ATSC demod)
The basic change is removing the single instance of the videobuf_dvb in
cx8802_dev and saa7134_dev(?) and replacing it with a list and some
supporting functions.
*NOTE* This branch was taken before v4l-dvb was closed for 2.6.19 so
two or three current cx88 patches appear to be reversed by this tree,
this will be cleaned up in the near future. The patches missing change
the mutex handing to core->lock, fix an enumeration problem."
It should be recognised that a number of people have been maintaining
this patchset. Significant levels of Kudos to everyone one involved,
including but not limited to:
Darron Broad
Fabio M. Di Nitto
Carlo Scarfoglio
Hans Werner
Without the work of these people, and countless others, my two year old
patches would of died on the Mercurial linuxtv.org vine a long time
ago.
TODO: Revise these patches a little further so that the need for
demux1 and dvr0 is optional, not mandatory on the HVR3000.
HISTORY (darron):
This is the last update to MFE prepared by Hans which is based
upon the `scratchpad' diff created by Carlo.
All MFE work prior to that point must be attributed to Fabio
who ported and maintained Steve's original patch up to that
time.

This patch against latest mercurial makes DVB-T working on Pinnacle
Hybrid PCTV Pro (pctv310c).
In cx88-dvb.c, a specific zl10353_config is created with the if2
inferred from the old comment in the currently used config. It is then
used for attach, and i2c_gate_ctrl is set to NULL.
The entry in cx88-cards.c is modified with GPIO gathered from windows
with regspy, and DVB enabled. The frontend is set to
XC3028_FE_ZARLINK456 to match the zl10353_config.
It is working great with the freeview channels I can receive.
