8c873d31af V4L/DVB (12744): em28xx: restructure fh/dev locking to handle both video and vbi
The current locking infrastructure didn't support having multiple fds accessing
the device (such as video and vbi).  Rework the locking infrastructure,
borrowing the design from cx88.

28abf083d3 V4L/DVB (12742): em28xx: add raw VBI support for NTSC
Add support for raw VBI capture for the em28xx bridge, currently only for
NTSC.  Support for PAL capture to follow shortly (including the removal of
numerous hard-coded NTSC-specific sizes for capture buffers, etc).

Note that the code currently changes the default current norm from PAL to
NTSC (so that zvbi-ntsc-cc works properly).  The default norm really should
be moved into a board-level parameter.

da52a55cff V4L/DVB (12741): em28xx: make video isoc stream work when VBI is enabled
Add code enabling the VBI registers for variants of the em28xx chip that
support VBI, and make sure the isoc streaming code continues to work for
the video component of the stream (note the video and vbi data arrive
intermixed on the same isoc pipe).

Note that this version just drops the actual VBI data onto the floor as
opposed to processing it.  The "#ifdef 0" tags are for the videobuf code that
appears in the next patch in this series.

We created a separate version of the isoc_copy version for parsing the version
of the stream that includes VBI data.  In theory, they might be able to be
merged at some point in the future, but the initial goal is to ensure that we
do not cause any regressions with devices that do not have VBI support.

   switched over to using 'tun->socket.sk' instead of the redundantly
   available (and thus removed) 'tun->sk', and 2b980dbd ("lsm: Add hooks

ac07bb73fe V4L/DVB (12712): em28xx: properly load ir-kbd-i2c when needed
Currently, the logic to load ir i2c ancillary module is broken. It is
associated to Hauppauge devices with IR flag on their eeprom, no matter
if the device uses i2c or em28xx direct IR support. That's wrong.

Instead, add a flag to the boards that use i2c IR chips and load the
module only for those devices and if ir is not disabled.

7aedd5ec87 V4L/DVB (12701): saa7134: ir-kbd-i2c init data needs a persistent object
ir-kbd-i2c's ir_probe() function can be called much later (i.e. at
ir-kbd-i2c module load), than the lifetime of a struct IR_i2c_init_data
allocated off of the stack in cx18_i2c_new_ir() at registration time.
Make sure we pass a pointer to a persistent IR_i2c_init_data object at
i2c registration time.

Thanks to Brian Rogers, Dustin Mitchell, Andy Walls and Jean Delvare to
rise this question.

Before this patch, if ir-kbd-i2c were probed after SAA7134, trash data
were used.

Compile tested only, but the patch is identical to em28xx one. So, it
should work properly.

Various frontend driver have parameter checks in their set_frontend
functions and return an error if the parameters are not supported,
tda10021 and cx24116 to name two.

The tuning ioctls FE_SET_FRONTEND/FE_SET_PROPERTY only change values
in the property cache and return before set_frontend is called. If a
set_frontend call in software zigzag algorithm fails and the card was
previously locked it will report a lock and the new parameters but is
still tuned to the old transport. This is not detectable from
userspace.

This change checks the return values of fe->ops.set_frontend and
changes the state to the added FESTATE_ERROR for software zigzag.
No lock will be reported to userspace if the State is FESTATE_ERROR.

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.

8d81ae2431 V4L/DVB (12613): cx25840: fix determining the firmware name
Depending on the model there are three different firmwares to choose from.
Unfortunately if a cx23885 is loaded first, then the global firmware name
is overwritten with that firmware and if ivtv is loaded next, then it
tries to load the wrong firmware. In addition, the original approach would
also overwrite any firmware that the user specified explicitly.

a65f315924 V4L/DVB (12612): si4713: simplify the code to remove a compiler warning.
The compiler warned about an uninitialized stereo variable. By simplifying
the code it 1) improved readability and 2) fixed the compiler warning.

a4c1cbc781 V4L/DVB (12600): dvb-usb-remote: return KEY_RESERVED if there's free space for new keys
The input subsystem checks if get_keycode works for a scan code. Due to that,
we need to return a valid value when there's some space at the table that
can be used by a scancode.

b77f0a7630 V4L/DVB (12599): dvb-usb-remote: Allow dynamically replacing the IR keycodes
Implements handler for EVIOCGKEYCODE/EVIOCSKEYCODE via adding two new callbacks
to the input device.

Since on dvb-usb a scan code has 16 bits, to fulfill rc5 standard codes, the default
getkeycode/setkeycode input methods would require the driver to spend up to 64 Kb of
a sparse table. Instead, add two new callbacks to the event device.

With this, it is now possible to replace the keycode tables. There are, however, a few
implementation details at the current patch:

1) It will replace the existing device keytable, instead of creating an instance
of the data. This works. However, if two devices pointing to the same table
were connected, changing the IR table of one will also change the IR table for
the other (the solution for this one is simple: just kmalloc some memory);

2) In order to change the scan code, you need first to change the key to
KEY_RESERVED or KEY_UNKNOWN to free some space at the table (solution: allocate
some additional space for newer scan codes or allow dynamic table grow);

3) The table size cannot be extended. It would be easy to allow the table to
grow dynamically: just calling kmalloc(size+1); kfree(old). Yet, maybe we can
just create a bigger table with a fixed size, like for example a table with 128
entries. This should be enough even for a very big IR.

The current issues should be addressed on a later patch.

2e3658836e V4L/DVB (12598): dvb-usb: store rc5 custom and data at the same field
In order to be closer to V4L IR implementation, it is needed to replace
	u8 custom, data
to:
	u16 scan

This allows using non-rc5 mappings, like the 8 bit keycodes used on older
protocols. It will also allow future implementations of rc6 keystrokes
when needed.

715a223323 V4L/DVB (12595): common/ir: use a struct for keycode tables
Currently, V4L uses a scancode table whose index is the scancode and
the value is the keycode. While this works, it has some drawbacks:

1) It requires that the scancode to be at the range 00-7f;

2) keycodes should be masked on 7 bits in order for it to work;

3) due to the 7 bits approach, sometimes it is not possible to replace
the default keyboard to another one with a different encoding rule;

4) it is different than what is done with dvb-usb approach;

5) it requires a typedef for it to work. This is not a recommended
Linux CodingStyle.

This patch is part of a larger series of IR changes. It basically
replaces the IR_KEYTAB_TYPE tables by a structured table:
struct ir_scancode {
       u16     scancode;
       u32     keycode;
};

This is very close to what dvb does. So, a further integration with DVB
code will be easy.

While we've changed the tables, for now, the IR keycode handling is still
based on the old approach.

The only notable effect is the redution of about 35% of the ir-common
module size:

   text    data     bss     dec     hex filename
   6721   29208       4   35933    8c5d old/ir-common.ko
   5756   18040       4   23800    5cf8 new/ir-common.ko

In thesis, we could be using above u8 for scancode, reducing even more the size
of the module, but defining it as u16 is more convenient, since, on dvb, each
scancode has up to 16 bits, and we currently have a few troubles with rc5, as their
scancodes are defined with more than 8 bits.

This patch itself shouldn't be doing any functional changes.
