Define a list of valid "firmware types" for each combination of BASE,
DTV and SCODEs. By masking the appropriate firmware bits off we can
just use one "type" for the firmware searching and also flag when we
are looking for a BASE, DTV or SCODE type firmware. This makes it
much easier to track if we need to change device modes or flash an
individual firmware part.
Add a structure to remember what firmware properties we have. This
contains the currently loaded/wanted base firmware (type), video std
(id), video std requested (std_req), scode file and number in use.
Incorporate said structure into the tuner private data.
When checking whether the current firmware needs to be reloaded, first
figure out exactly what "type" of firmware we want (base, std and
scode), and then proceed to load the appropriate matching base,
std-specific and scode records iff there are any changes required.
This removes guesswork from the process because we no longer need to
individually code a check for every tuning parameter's interactions.

Xceive 2028/3028 has a concept of scode/dcode.
Scode is a table of 16 values (each with 12 bytes i2c sequence).
Dcode is the entry of Scode table that should be used, given a certain
frequency.
The idea is that, depending on what frequency is selected, and according with a
country-based (or standard-based?) table, the Xceive should be "hacked" to
fine-tune that specific frequency.
By default, Scode=0 is used, for undefined frequencies. Also, Scode=0 seems to
be the most used value.
This patch adds the capability of selecting a scode. However, extra work will
be needed to allow auto-selecting the proper scode, for a given set of
frequencies.
I'm not sure what would be the proper way for implementing the dcode selection.

This is necessary for capture apps like MPlayer that use different threads for

It also removes some locks that look unnecessary:
In em28xx_init_dev:
the videodevice is not registered yet so nothing can access the hardware
meanwhile, the device struct is not assigned to the interface yet so no race
with disconnect is possible

controlled by the analog demodulator. We already have a method to control
such i2c gates when they are controlled by the digital demodulator, but in
some hybrid designs, there may be an i2c gate controlled by each demodulator.
For example, when in analog tuning mode, one would access the tuner by opening
the i2c gate controlled by the analog demodulator, while when in digital
tuning mode, one would access the tuner by opening the i2c gate controlled by
the digital demodulator.

This board has some special tea5767 configuration. Basically, radio
XTAL uses a different frequency than the other supported radios. It
uses a 13 MHz XTAL.
This patch adds the proper radio gpio and tea5767 configurations for
the board.
Also, with PAL/BG, the board requires some special init for tda9887:
port1=0 port2=0 qss=1
Thanks to Serge Kolotylo and MIDImaster for their help on identifying
the proper needs for this driver.

tea5767 has several possible configurations. Before the patch, the
driver were assuming the more common configuration. However, some newer
cards, like MSI @nyware Master requires other configurations, like
de-activating a gpio port and changing chip Xtal.
This patch adds the capability of altering device configuration at
runtime. This may also be used later to activate some features like
auto-mute when signal is weak.

Currently, the only tuner-specific device that allows special
configurations is tda9887. However, tea5767 also may require some
special configurations (for example, to specify a different Xtal freq).
This patch replaces TDA9887_SET_CONFIG by a more generic internal ioctl
(TUNER_SET_CONFIG). The newer one allows specifying what tuner is
appliable to a configuration set, and allows an arbitrary configuration
struct.

The saa7134 video driver starts dropping frames when used together with the
saa7134-alsa driver. Frames are dropped because when an audio event is waiting
the driver simply ignores the interrupt and passes it on to the saa7134-alsa
interrupt handler. The alsa interrupt handler in turn acknowledges all types
of events thus clearing the pending video events as well. Fix by only masking
out the audio event in the video interrupt handler and by only acknowledging
the audio event in the alsa driver.

This em28xx-video.c uses functions from this header, but doesn't include it.

These v4l headers might change, so it's best to include the headers needed

It also causes problems for the out of core build system's backward

The pvrusb2 driver's sysfs implementation had long since implemented a
dummy hotplug function because at the time the kernel would oops
without at least the empty function being present. Today - after
numerous class interface changes in the kernel - this pvrusb2 change
had been dutifully carried forward but an inspection of the kernel
sources shows that it is no longer needed. So remove the dummy
function and its reference. This also solves a recurring backwards
compatibility issue in the pvrusb2 driver as the class interface has
been getting thrashed in the kernel.

The V4L1 spec says that the image size should be with with VIDIOCSWIN before
requesting buffers with VIDIOCGMBUF and capturing into them with
VIDIOCMCAPTURE.
But it seems that many apps don't do this. They set the size using the fields
in the VIDIOCMCAPTURE ioctl. The driver doesn't know what size to capture
until it actually starts to capture. In particular, it doesn't know what size
to capture until it has already mmap the captured buffers. Which is quite
stupid. Why V4L1 has size and format fields for VIDIOCMCAPTURE I have no idea.
Many drivers don't support this, including those using v4l1-compat.
The bttv does, which is probably the only reason such broken software is so
prevalent.
But, the driver doesn't adjust its idea of what size is being captured when it
is set this way. If you try to query the driver's current setting with
v4l2-ctl, it won't be correct.

The bttv driver instists that the depth specified in the call to VIDIOCSPICT
match the pixel format specified in the same call.
vlc doesn't set the depth field, which makes the SPICT ioctl always fail.
The V4L1 standard is not clear on how most operation are supposed to work, and
this is no exception. The depth field would appear to be entirely redundant,
as the pixel format specifies a specific depth. It could be that this field
was only meant for output from the *G*PICT ioctl and should be ignored in
*S*PICT. This is in fact what the v4l1-compat wrapper does.

When the ivtvfb module is loaded, the YUV output is relative to the
framebuffer output. When a virtual screen size is used, the output area for
the YUV may actually be off screen. To prevent the hardware from crashing,
the current driver will ignore an off-screen position and leave the output
visible at the last on-screen position. This may not be desirable, so this
patch will switch off the YUV output should the image move off-screen, and
re-enable it should the image move on-screen again.

It was a struct cx8802_driver for no apparent reason. Nothing uses a
cx8802_driver in the cx8802_dev struct. The only field that was used was
devlist, a list_head.
The code in cx8802_remove() that removed any loaded sub-drivers was broken.
It would delete the current list entry, but didn't use list_for_each_safe. It
also called list_del() on the list _head_ inside the list_for_each loop? It
would crash if it was run, which I don't think can ever happen.
Since the cx8802 sub-drivers use the cx8802 driver, they have to be unloaded
first. So there isn't any way for a sub-driver to still be loaded when
cx8802_remove() is called... Except maybe with PCI hot-plug, if one removes
the PCI card while the drivers are loaded?
So I left some code in to handle that if it's actually possible. It will
remove the sub-drivers from the device cx8802_remove() was called on, and only
that device. If one has two DVB cards and unplugs one, there is no reason to
unload the DVB drivers for both cards. I have no way to test this, but it
can't be worse than what was there before.
cx8802_get_driver() is passed a cx8802_dev pointer and looks for the requested
driver on that device. It first loops over the cx8802 device list looking for
the device it was passed, which is pointless. It doesn't need to find the
device pointer in the list, as it already has the pointer.
The list_head in the cx8802_driver struct, which joins all the _drivers_
attached to a device, was named devlist. Changed that to drvlist, since the
devlist is used for a list of _devices_ in other cx8802 structs.

Add two mute controls. One mutes everything, the other just mutes the analog

Rename the existing volume control. The controls are now:
Playback Volume
Playback Switch
Capture Switch
These names might seem odd, but I believe they are more correct. The previous
"Capture Volume" control didn't actually effect the volume of the captured
audio. Instead it controls the volume of the analog pass-thought output. It
appears that pass-through controls like this are usually considered to be in
the playback direction, not capture. For example, "CAPTURE feedback Playback
Volume" is the name used for a control that appears to have the same effect in
the ca0106 driver. We only have one volume control, so we can omit the
"CAPTURE feedback" part.
If someone where to add PCM playback support to the driver, then this would be
the volume control.

By default, we allocate DMA buffers when actually reading from the video
capture device. On a system with 128MB or 256MB of ram, it's very easy
for that memory to quickly become fragmented. We've had users report
having 30+MB of memory free, but the cafe_ccic driver is still unable to
allocate DMA buffers.
Our workaround has been to make use of the 'alloc_bufs_at_load' parameter
to allocate DMA buffers during device probing. This patch makes DMA
buffer allocation happen during device probe by default, and changes
the parameter to 'alloc_bufs_at_read'. The camera hardware is there,
if the cafe_ccic driver is enabled/loaded it should do its best to ensure
that the camera is actually usable; delaying DMA buffer allocation

I2C adapters should only support I2C_M_REV_DIR_ADDR if they really have
to (i.e. if they are connected to a broken I2C device which needs this

The v4l tveeprom logic tells us what video standards are supported by
the hardware, however it doesn't directly tell us what should be the
preferred initial standard. For example "NTSC/NTSC-J" devices are
reported by tveeprom as support NTSC-M and PAL-M, and while that might
be true, in the vast majority of cases NTSC-M is really what the user
is going to want. However the driver previously just arbitrarily
picked the "lowest numbered" standard as the initial default, which in
that case would have been PAL-M. (And making matters more confusing -
this only caused real problems on 24xxx devices because the saa7115 on
29xxx seems to autodetect the right answer anyway.) This change
implements an algorithm that uses the set of "supported" standards as
a hint to decide on the initial standard. This algorithm ONLY comes
into play if the driver isn't specifically told what to do; said
another way - the user can always still change the standard via the
sysfs interface, via the usual V4L methods, or even specified as a
module parameter. The idea here is only to pick a better starting
point if the user (or app) doesn't otherwise do something to set the
standard; otherwise this change has no real impact.

The pvrusb2 driver already has a method for extracting the FX2's

facilitate manual firmware extraction as per the procedure documented
on the pvrusb2 web site. This change follows that pattern and
implements a corresponding method to grab the binary contents of the
PVR USB2 prom (which for PVR USB2 devices can contain information in

Use the balance control to make the mono volume control stereo.
Note that full range isn't supported. The balance control attenuates one
channel by 0 to -63 dB, and the volume control provides additional attenuation
to both channels by another 0 to -63 dB.
So the channel with the most attenuation has a range of 0 to -126 dB, while
the other channel only has a range of 0 to -63 dB. ALSA volume controls don't
appear to support this concept. I just limited the range to 0 to -63 total.
Once you get to -63 dB, you're already at silence, so additional attenuation
is pretty much pointless anyway.

The tuner module has a rather aggressive range of possible i2c addresses.
As per the specs available, it appears as if there are no 4-byte tuners that
actually use i2c addresses in the range 0x64 thru 0x6f, yet, tuner-core claims
the address range 0x60 thru 0x6f.
Allowing tuner.ko to probe these addresses can cause potential damage to
certain IR receivers, RTC chips or any other IC's that might otherwise reside
on the i2c bus using one of these addresses.
The plan is to remove these i2c addresses from the i2c address range of the
tuner module. If any devices are discovered that actually do have tuners at
one of these addresses, the newer i2c probing methods will be used to handle
those cases.
In order to collect this information and avoid any potential regressions,
the following warning has been added upon successful detection of a tuner
using an i2c address in the range 0x64 thru 0x6f:

Rework the way the DMA buffer is handled and IRQs are generated.
ALSA uses a ring-buffer of multiple periods. Each period is supposed to
corrispond to one IRQ.
The existing driver was generating one interrupt per ring-buffer, as opposed
to per period. This meant that as soon as the IRQ was generated, the hardware
was already starting to re-write the beginning of the buffer. Since the DMA
happens on a per-line basis, there was only a narrow window to copy the data
out before the buffer was overwritten.
The cx88 core RISC program generator is modified so that it can set the IRQ
and counter flags to count every X lines of DMA transfer. This way we can
generate an interrupt every period instead of every full ring-buffer. Right
now only period of one line are supported, but it should be possible to
support longer periods. Note that a WRITE instruction generates an IRQ when
it starts, not when the transfer is finished. Thus to generate an IRQ when
line X is done, one must set the IRQ flag on the instruction that starts line
X+1, not the one that ends line X.
Change the line size so that there are four lines in the SRAM FIFO. If there
are not four lines, the analog output from the cx88's internal DACs is full of
clicks and pops.
Try to handle FIFO sync errors. Sometimes the chip generates many of these
errors before audio data starts. Up to 50 sync errors will be ignored and the
counter reset.
Have the IRQ handler save the RISC counter to the chip struct, and then have
the pointer callback use this to calculate the pointer position. We could
read the counter from the pointer callback, but sometimes the sync errors on
start up cause the counter to go crazy. ALSA sees this and thinks there has
been an overrun. The IRQ hander can avoid saving the counter position on
sync errors.
The chip "opened" flag wasn't necessary. ALSA won't try to open the same
substream multiple times. Probably this code was cut&pasted from the bt87x
driver, which has multiple sub-streams for one chip.
Do error checking for the videobuf mapping functions.
snd_card_cx88_runtime_free() is useless and can be deleted.

Currently the driver turns on audio interrupts, then sets the audio interrupt
mask to select which interrupts to get. One could received unwanted
interrupts since the mask is set _after_ interrupts have already been turned
on. Change the order of the operations, and clear any audio interrupt status
bits that are already set for good measure.
Before changing the SRAM FIFO parameters, make sure the FIFO isn't being used.
This shouldn't happen with just the ALSA driver, as it should never try to
turn on FIFO/RISC/DMA while they are already on. However, the V4L driver
needs to turn the audio FIFO on for analog audio output to work (undocumented
cx88 bug). The FIFO parameters are in an inconsistent state while they are
updated, and this results in many FIFO sync error IRQs if the FIFO is in use
while it's in this inconsistent state.
Also create and use a bunch of symbolic constants for audio interrupt mask
bits.

Get rid of the "CORE" prefix from cx88 printks. It was only used a few times,

The cx88 driver state stored the ID of the board type in core->board. Every
time the driver need to get some information about the board configuration, it
uses the board number as an index into board configuration array.
This patch changes it so that the board number is in core->boardnr, and
core->board is a copy of the board configuration information. This allows
access to board information without the extra indirection. e.g.
cx88_boards[core->board].mpeg becomes core->board.mpeg.
This has a number of advantages:
- The code is simpler to write.
- It compiles to be smaller and faster, without needing the extra array lookup
to get at the board information.
- The cx88_boards array no longer needs to be exported to all cx88 modules.
- The boards array can be made const
- It should be possible to avoid keeping the (large) cx88_boards array around
after the module is loaded.
- If module parameters or eeprom info override some board configuration

Add radio support for the Thomson DTT7612 tuner.
This tuner uses a different 1st intermediate frequency than the other radio
tuners supported (a lot of NTSC radio tuners probably need this change too).
Add a new tuner-simple parameter, radio_if. It selects the 1st IF used for
radio reception. The radio frequency setting code in tuner-simple now uses
this field, instead of a special case select() block for each tuner with radio
support.
The tuner parameters for tuners that used a 33.3 MHz RIF now set radio_if to 1
in tuner-types.c.
The Thomson DTT7612 gets radio_if = 2, also add has_tda9887 = 1 and
fm_gain_normal = 1.
Add some defines for tda9887 bits that control IF setting in radio mode.
Add a new tda9887 config option, TDA9887_RIF_41_3, that selects a 41.3 MHz
radio IF.
Fix the way tda9887 radio options work. The driver was modifying the default
radio mode config templates based on the TDA9887_XXXX flags. This means that
_all_ tuners would get the same settings. If you had a one tuner than used
TDA9887_GAIN_NORMAL and one that didn't, both would get the setting. Now the
tda9987 driver just checks if tuner mode is radio and then applies the config
settings directly to the data being sent, just like how all the TV mode
settings already work.
The PLL setting math is made a little more accurate.

order is changed mid stream, the driver will ensure that the previous frame

This patch adds an internal ioctl-like interface which can be used in
situations where a single Video4Linux device is implemented by multiple
device drivers. One master device controls one or more slave devices.
The slaves provide Video4Linux ioctl-like interface for the use of the
master.
Only a handful of ioctls are implemented at the moment. More can (and
should) be added as more functionality is required.

Using udma yuv causes the driver becomes locked into that mode. This prevents
use of the mpeg decoder & non-udma yuv output. This patch clears the
operating mode when the device is closed.

Fix a couple drivers that do not correctly terminate their pci_device_id
lists. This results in garbage being spewed into modules.pcimap when the
module happens to not have 28 NULL bytes following the table, and/or the
last PCI ID is actually truncated from the table when calculating the
modules.alias PCI aliases, cause those unfortunate device IDs to not
auto-load.

Right now the composite sound input doesn't work on AverTV 307 because of
the wrong mux setup. The composite sound is routed via an external
4channel multiplexer controlled by GPIO, while the code assumes an internal
multiplexer instead.
Presumably this was a copy/paste error, and noone have ever tested the
functionality.
With the attached patch it works properly, which gives me an ability to
finally watch the cable TV under linux.

Due to a documentation bug (the type mask is 3 bits long, not 2) the wrong
frame types were filled in: the B and P frame types were swapped.
This bug also hid a second bug: when a capture is stopped a last entry is
written into the pgm index buffer with internal type 0, denoting the end
of the program. This entry wasn't ignored, instead it was accidentally
returned to the caller as a P frame.

the pwc driver has a disconnect method that waits for user space to
close the device. This opens up an opportunity for a DoS attack,
blocking the USB subsystem and making khubd's task busy wait in
kernel space. This patch shifts freeing resources to close if an opened
device is disconnected.

If, in em28xx_usb_probe() the memory allocation
dev->alt_max_pkt_size = kmalloc(32*
dev->num_alt,GFP_KERNEL);
fails, then we'll bail out and return -ENOMEM.
The problem is that in that case we don't free the storage allocated
to 'dev', thus causing a memory leak.
This patch fixes the leak by freeing 'dev' before we return -ENOMEM.
This fixes Coverity bug #647.

Configuring the OLPC camera requires something over 150 register
writes. Unfortunately, querying the CAFE i2c controller too
soon after a write causes the hardware to flake. The problem had
been "solved" with an msleep() call, but, between the number of
registers and how msleep() behaves, that resulted in a 3-second
delay on camera initialization. Instead, we hand-code a wait for
the completion interrupt which avoids reading the status registers.

While decoding (MPEG or YUV) is active or when VBI output is in use, then
do not clear the VBI output of the saa7127. Only after the last user is
gone can we clear it.
This fixes the case where playback was stopped, another channel was chosen
and playback was restarted, while /dev/vbi16 was used to set the WSS
(widescreen) setting. Without this fix the WSS was reset on every stop
instead of just keeping the last value.

s_register was assigning the return code to (unsigned)reg->val, rather than
errCode, which it what it would return. Except reg->val can't be < 0, so it
would never actually return an error.

Various gpio and mux settings for the Osprey 440 weren't correct. Fix them
and provide some documentation about how the gpios work.
The osprey eeprom routine wasn't run for the 440, add it. It was also crap,
re-written to be better.
Add the Osprey 440 to the Bt878 ALSA driver's whitelist. Currently the sample
rate is fixed at 32kHz, as the driver doesn't support different rates for
digital input mode, though the card can select the rate from 32, 44.1, or 48
kHz via gpio.
Setting the audio gain via ALSA isn't supported yet; a userspace tool that
programs the X9221 via i2c-dev must be used.
The Bt878 digital audio format isn't programmed correctly for the CS5331A ADC
used, resulting in extremely garbled sound. That is fixed in a followup
patch.
