Remove the vtx (aka videotext aka teletext) API from the v4l2 core.
This API was scheduled for removal in kernel 2.6.35.
The vtx device nodes have been superseded by vbi device nodes
for many years. No applications exist that use the vtx support.
Of the two i2c drivers that actually support this API the saa5249
has been impossible to use for a year now and no known hardware
that supports this device exists. The saa5246a is theoretically
supported by the old mxb boards, but it never actually worked.
In summary: there is no hardware that can use this API and there
are no applications actually implementing this API.
The vtx support still reserves minors 192-223 and we would really
like to reuse those for upcoming new functionality. In the unlikely
event that new hardware appears that wants to use the functionality
provided by the vtx API, then that functionality should be build
around the sliced VBI API instead.

This patch makes in-kernel decoding with the stock Streamzap PC Remote
work out of the box. There are quite a few things going on in this
patch, all related to getting this working:
1) I had to enable reporting of a long space at the end of each signal,
or I had weird buffering and keybounce issues.
2) The keymap has been reworked slightly to match actual decoded values,
the first edition was missing the pre-data bits present in the lirc
config file for this remote.
3) There's a whole new decoder included, specifically for the
not-quite-RC5 15-bit protocol variant used by the Streamzap PC
Remote. The decoder, while usable with other recievers (tested with
an mceusb receiver), will only be loaded by the streamzap driver, as
its likely not of use in almost all other situations. This can be
revisited if/when all keytable loading (and disabling of unneeded
protocol decoder engines) is moved to userspace, but for now, I think
this makes the most sense.
Note that I did try to enable handling the streamzap RC5-ish protocol in
the current RC5 decoder, but there's no particularly easy way to tell if
its 14-bit RC5 or 15-bit Streamzap until we see bit 14, and even then,
in testing an attempted decoder merge, only 2/3 of the keys were
properly recognized as being the 15-bit variant and decoded correctly,
the rest were close enough to compliant with 14-bit that they were
decoded as such (but they have overlap with one another, and thus we
can't just shrug and use the 14-bit decoded values).
Also of note in this patch is the removal of the streamzap driver's
internal delay buffer. Per discussion w/Christoph, it shouldn't be
needed by lirc any longer anyway, and it doesn't seem to make any
difference to the in-kernel decoder engine. That being the case, I'm
yanking it all out, as it greatly simplifies the driver code.

The old usbvideo ibmcam driver needs to be replaced with a v4l2 driver
preferably using the gspca webcam framework rather then the old usbvideo
framework.
This new gspca sub driver sets a first step in that direction. The ibmcam
driver supports 4 different model webcams. This new driver (for now) only
supports Model 3 cameras, as my test cam is a Model 3 cam, or so I thought.
Upon reading:
http://www.linux-usb.org/ibmcam/
I learned that the IBM Netcamera Pro I have even though having the same
usb id and the same bcd version is different from the Model 3 cameras
supported by the ibmcam driver. So this new gscpa subdriver supports Model 3
cameras (untested), and the IBM Netcamera Pro. Currently use with the
IBM Netcamera Pro requires a module parameter. I hope to be able to
autodetect which is which in the future.

The compat code for the VIDIOCSMICROCODE ioctl is totally buggered.
It's only used by the VIDEO_STRADIS driver, and that one is scheduled to
staging and eventually removed unless somebody steps up to maintain it
(at which point it should use request_firmware() rather than some magic
ioctl). So we'll get rid of it eventually.
But in the meantime, the compatibility ioctl code is broken, and this
tries to get it to at least limp along (even if Mauro suggested just
deleting it entirely, which may be the right thing to do - I don't think
the compatibility translation code has ever worked unless you were very
lucky).

All file_operations should get a .llseek operation so we can make
nonseekable_open the default for future file operations without a
.llseek pointer.
The three cases that we can automatically detect are no_llseek, seq_lseek
and default_llseek. For cases where we can we can automatically prove that
the file offset is always ignored, we use noop_llseek, which maintains
the current behavior of not returning an error from a seek.
New drivers should normally not use noop_llseek but instead use no_llseek
and call nonseekable_open at open time. Existing drivers can be converted
to do the same when the maintainer knows for certain that no user code
relies on calling seek on the device file.
The generated code is often incorrectly indented and right now contains
comments that clarify for each added line why a specific variant was
chosen. In the version that gets submitted upstream, the comments will
be gone and I will manually fix the indentation, because there does not
seem to be a way to do that using coccinelle.
Some amount of new code is currently sitting in linux-next that should get
the same modifications, which I will do at the end of the merge window.
Many thanks to Julia Lawall for helping me learn to write a semantic
patch that does all this.

This fixes a nasty memory corruption bug when using userptr I/O.
The function videobuf_pages_to_sg() sets up the scatter-gather list for the
DMA transfer to the userspace pages. The first transfer is setup correctly
(the size is set to PAGE_SIZE - offset), but all other transfers have size
PAGE_SIZE. This is wrong for the last transfer which may be less than PAGE_SIZE.
Most, if not all, drivers will program the boards DMA engine correctly, i.e.
even though the size in the last sg element is wrong, they will do their
own size calculations and make sure the right amount is DMA-ed, and so seemingly
prevent memory corruption.
However, behind the scenes the dynamic DMA mapping support (in lib/swiotlb.c)
may create bounce buffers if the memory pages are not in DMA-able memory.
This happens for example on a 64-bit linux with a board that only supports
32-bit DMA.
These bounce buffers DO use the information in the sg list to determine the
size. So while the DMA engine transfers the correct amount of data, when the
data is 'bounced' back too much is copied, causing buffer overwrites.
The fix is simple: calculate and set the correct size for the last sg list
element.

[ 1351.281284] ir_keyup: keyup key 0x0067
ie one key down event and one key up event 250ms later.
So, we need to increase the repeat timeout, to avoid this bug to hit.

Conexant cx231xx + Fujitsu 86A20S demodulator. However, both shares

We know for sure that bcd 0x100 is used for a dib0700 device, while
bcd 0x4001 is used for a cx23102 device. This patch reserves two ranges,
the first one from 0x0000-0x3f00 for dib0700, and the second from

This may need fixes in the future, as we get access to other devices.

The original code dereferenced "port" before checking it for NULL. I
moved the test down below the check. Also I changed the comparisons a
little so people wouldn't get confused and think "port" and "buf" were

the first place.)

502). Note that beginning with linux kernel version 2.6.32 the
modulation method is checked (by function dvb_frontend_check_parameters

developers much easier.
Note that this patch moves some of the control support that used to be in
v4l2-common.c to v4l2-ctrls.c. The tables were copied unchanged. The body
of v4l2_ctrl_query_fill() was copied to a new v4l2_ctrl_fill() function
in v4l2-ctrls.c. This new function doesn't use the v4l2_queryctrl
struct anymore, which makes it more general.
The remainder of v4l2-ctrls.c is all new. Highlights include:
- No need to implement VIDIOC_QUERYCTRL, QUERYMENU, S_CTRL, G_CTRL,
S_EXT_CTRLS, G_EXT_CTRLS or TRY_EXT_CTRLS in either bridge drivers
or subdevs. New wrapper functions are provided that can just be plugged in.
Once everything has been converted these wrapper functions can be removed as well.
- When subdevices are added their controls can be automatically merged
with the bridge driver's controls.
- Most drivers just need to implement s_ctrl to set the controls.
The framework handles the locking and tries to be as 'atomic' as possible.
- Ready for the subdev device nodes: the same mechanism applies to subdevs
and their device nodes as well. Sub-device drivers can make controls
local, preventing them from being merged with bridge drivers.
- Takes care of backwards compatibility handling of VIDIOC_S_CTRL and
VIDIOC_G_CTRL. Handling of V4L2_CID_PRIVATE_BASE is fully transparent.
CTRL_CLASS controls are automatically added.

This ports lirc_streamzap.c over to ir-core in-place, to be followed by
a patch moving the driver over to drivers/media/IR/streamzap.c and
enabling the proper Kconfig bits.
Presently, the in-kernel keymap doesn't work, as the stock Streamzap
remote uses an RC-5-like, but not-quite-RC-5 protocol, which the
in-kernel RC-5 decoder doesn't cope with. The remote can be used right
now with the lirc bridge driver though, and other remotes (at least an
RC-6(A) MCE remote) work perfectly with the driver.
I'll take a look at making the existing RC-5 decoder cope with this odd
duck, possibly implement another standalone decoder engine, or just
throw up my hands and say "meh, use lirc"... But the driver itself
should be perfectly sound.
Remaining items on the streamzap TODO list:
- add LIRC_SET_REC_TIMEOUT-alike support
- add LIRC_GET_M{AX,IN}_TIMEOUT-alike support
- add LIRC_GET_REC_RESOLUTION-alike support
All of the above should be trivial to add. There are patches pending to
add this support to ir-core from Maxim Levitsky, and I'll take care of
these once his patches get integrated. None of them are currently
essential though.

This patch is primarily a port of the integrated IR controller code in
cx23885/cx23888-ir.c. Right now, only the CX2388[57] AV core will
really try to set up IR. This IR support, by design, still requires the
bridge driver to do final IO pin mux configuration and setup of the IR
controller parameters.
For the CX2388[578] chips, enabling the AV Core for IR also starts
sending Audio and Video interrupts to the bridge driver. For
CX2388[578] chips audio and video interrupts are ignored and
acknowledged when they happen.
IR interrupt handling and status logging is exluded for the CX23888
which does not have an IR controller on the AV core.
Note that experimentation reveals that the IR irq enables on the
CX23885 have an inverted logic sense. The CX23887 likely suffers from
the same quirk. For these chips, those irq enable bits are handled
as interrupt disables.

Rewrites the siano IR implementation. The previous implementation were
non-standard. As such, it has issues if more than one device registers IR,
as there used to have some static constants used during protocol decoding
phase. Also, it used to implement its on RAW decoder, and only for RC5.
The new code uses RC core subsystem for handling IR. This brings several
new features to the driver, including:
- Allow to dynamically replace the IR keycodes;
- Supports all existing raw decoders (JVC, NEC, RC-5, RC-6, SONY);
- Supports lirc dev;
- Doesn't have race conditions when more than one sms IR is
registered;
- The code size for the IR implementation is very small;
- it exports the IR features via /sys/class/rc.

This patch implements change_protocol callback. With this change,
there's no need for an extra modprobe parameter to specify the
protocol. When a table is loaded (either from in-kernel rc-map
tables or via ir-keytable program), the driver will automatically
change the protocol, in order to work with the given table.

This patch fixes possible race conditions in queue management with SMP:
when a frame was completed, the irq function tried to use the next frame
buffer. At this time, it was possible that the application on an other
processor updated the frame pointer, making the image to point to a bad
buffer.
The patch contains two main changes:
- the image transfer uses the queue indexes which are protected against
simultaneous memory access,
- the image pointer which is used for image concatenation is only set at
interrupt level.
Some subdrivers which used the image pointer have been updated.

- just after clearing the bit V4L2_BUF_FLAG_QUEUED and before setting
the bit V4L2_BUF_FLAG_DONE, on the other processor, the application
tries to requeue the same frame buffer,
- then, the qbuf function succeeds because ALL_FLAGS are not set.

Spent a while last night getting device initialization packet captures
under Windows for all generations of devices. There are a few places
where we were doing things differently, and few things we were doing
that we don't need to do, particularly on gen3 hardware, and I *think*
one of those things is what was locking up my pinnacle hw from time to
time -- at least, its been perfectly well behaved every time its been
plugged in since making this change.
First up, we're adding a bit more to the gen1 init routine here. Its
not absolutely necessary, the hardware works the same both with and
without it, but I'd like to be consistent w/Windows here.
Second, DEVICE_RESET is never called when initializing either of my
gen3 devices, its only called for gen1 and gen2. The bits in the gen3
init after removing that, are safe (and interesting) to run on all
hardware, so there's no more gen3-specific init done, there's instead
a generic mceusb_get_parameters() that is run for all hardware.
Third, the gen3 flag isn't needed. We only care if hardware is gen3
during probe, so I've dropped that from the device flags struct.
Successfully tested on all three generations of mceusb hardware.

Since commit b402843787
the 'driver_data' field resides in device's struct device_private
which may be allocated by dev_set_drvdata() if device_private
struct was not allocated previously.
dev_set_drvdata() is used in video_set_drvdata() to set
the driver's private data pointer in v4l2 drivers. Setting
the private data _before_ registering the v4l2 device results
in a memory leak since __video_register_device() also calls
video_set_drvdata(), but after zeroing the device structure.
Thus, the reference to the previously allocated device_private
struct goes lost and a new device_private will be allocated.
All v4l drivers which call video_set_drvdata() _before_
calling video_register_device() are affected. The patch fixes
__video_register_device() to preserve previously allocated
device_private reference.

Since there is no flag in the SI data that would indicate
that a transponder uses "turbo fec", VDR will assume that

The first-gen mceusb device init code, while mostly functional, had a few
issues in it. This patch does the following:
1) removes use of magic numbers
2) eliminates mapping of memory from stack
3) makes debug spew translator functional
Additionally, this clean-up revealed that we cannot read the proper default
tx blaster bitmask from the device, we do actually have to initialize it
ourselves, which requires use of a somewhat gross list-based mask inversion
check.
This patch also removes the entirely unnecessary use of struct ir_input_state.
Also supersedes two earlier patches that also touched on first-gen
cleanup, but were partially botched. This one actually compiles, works,

This patch moves the state from each raw decoder into the
ir_raw_event_ctrl struct.
This allows the removal of code like this:
spin_lock(&decoder_lock);
list_for_each_entry(data, &decoder_list, list) {
if (data->ir_dev == ir_dev)
break;
}
spin_unlock(&decoder_lock);
return data;
which is currently run for each decoder on each event in order
to get the client-specific decoding state data.
In addition, ir decoding modules and ir driver module load
order is now independent. Centralizing the data also allows
for a nice code reduction of about 30% per raw decoder as
client lists and client registration callbacks are no longer
necessary (but still kept around for the benefit of the lirc
decoder).
Out-of-tree modules can still use a similar trick to what
the raw decoders did before this patch until they are merged.

While rc-5 and rc-6 protocols are generally abreviated as "rc5" and "rc6",
previous sysfs nodes uses rc-5 and rc-6 for the Philips protocols. This is
consistent with the protocol nomenclature given by the original Philips
spec: "Remote control system RC-5" (doc. Nr. 9398 706 23011).
Also, rc5 is the name of a widely known cryptography protocol.
So, the better is to keep referring to those protocols as "rc-5" and "rc-6".

With the current logic, each raw decoder needs to add a copy of the exact
same sysfs code. This is both unnecessary and also means that (re)loading
an IR driver after raw decoder modules have been loaded won't work as
expected.
This patch moves that logic into ir-raw-event and adds a single sysfs
file per device.
Reading that file returns something like:
"rc5 [rc6] nec jvc [sony]"
(with enabled protocols in [] brackets)
Writing either "+protocol" or "-protocol" to that file will
enable or disable the according protocol decoder.
An additional benefit is that the disabling of a decoder will be
remembered across module removal/insertion so a previously
disabled decoder won't suddenly be activated again. The default
setting is to enable all decoders.
This is also necessary for the next patch which moves even more decoder
state into the central raw decoding structs.
