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,
and it makes it look like they're coming from the kernel core or something.
Fix the message, "TV tuner 60 at 0x1fe, Radio tuner -1 at 0x1fe", by adding a
"cx88[0]" prefix to be consistent, and to keep people who grep their dmesg
output for cx88 from missing it. Get rid of the addresses, which are always
wrong. The addresses are always set to -1, but because it's an unsigned 8-bit
value, the left shift converts it to the nonsense address 0x1fe.
In the cx8802 driver, some cut and pasted code prefixed lines with "CORE
cx88[0]:", which has been changed to "cx88[0]/2:" like the other printks from
the cx8802 driver.

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
setting, it's not necessary to modify the boards array, which would
affect all boards of the same type.

impossible to detect whether the audio was muted by the user or if it
was muted due to the microcontroller trying to detect the audio

I've changed the range to the lowest channel - 1/2 bandwidth and the

frequency ranges must be part of the tuner and not of the frontend

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.
And a grammar error in a printk is fixed.

In the current driver, the field order is global. As soon as it's changed it
takes immediate effect. This is a problem when the video changes order mid
stream. Although it mostly works okay, the video may judder / flicker.
This patch attaches the field order to the frame, so that any buffered frames
will not be displayed until the correct field. In the event that the field
order is changed mid stream, the driver will ensure that the previous frame
is displayed for a minimum of 3 fields. These are the two original fields the
frame should have occupied, plus the one extra since the new frame still has
to wait for the correct field.

Debugging cleanups to the zr36067 driver:
* Use module_param_named() to declare the debug parameter, so we can
use a single global variable to handle the debug level. This makes
the driver a bit smaller (by 648 bytes on x86_64), thanks to one
less level of indirection on every use.
* Change the debug parameter sysfs permissions, so that the debug
level can be adjusted at runtime, as is done in many other
media/video drivers.
* The debug level is between 0 and 5, not 0 and 4.
* Move the zr_debug export and dprintk macro definition to a header
file so that we don't have to define them in each source file.
* Simplify a duplicate test on zr_debug.

Git changeset 6bdcc6e6db dropped the
stand-alone lgh06xf module, whose functionality was absorbed into the
dvb-pll module. However, there was a minor difference between the code
in lgh06xf and dvb-pll, which caused a regression in b2c2-flexcop
devices using the LG-H06xF NIM.
dvb-pll will probe for the presence of an i2c pll chip by performing a
single byte read, the lgh06xf driver did not do this. Unfortunately, the
code in flexcop-i2c.c does not currently support 1 byte or 0 byte reads
as a probe. Such probes with the current code will always fail.
In order to work around this problem, and restore proper functionality
of the Airstar HD5000 device, this hack was created to make the probe
appear to succeed. The single byte read in dvb_pll_attach is the only
place where such a probe would ever occur, so this change is safe, and
will not affect any other devices.
Of course, if one knew how to actually perform the read operation, it
would be better to go that route. In the meantime, however, we must
apply this workaround, in order to prevent the regression that causes
tuning to fail on the Airstar HD5000 ATSC device.
Thanks to Jarod Wilson, who had originally reported this regression, and
to Geoffrey Hausheer, whose original workaround patch led us to find the
actual cause of the problem.

soon after a write causes the hardware to flake. The problem had

than use some if and switch statements to set to register by looking at the

During uncompressed capture, the poll() function was looking the wrong frame.
It was using the frame the driver was going to capture into next (pend_tail),
when it should have been looking at the next frame to be de-queued with
DQBUF/SYNC (sync_tail).
It also wasn't looking in the right spot. It was looking at the file handle's
copy of the buffer status, rather than the driver core copy. The interrupt
routine marks frames as done in the driver core copy, the file handle copy
isn't updated. So even if poll() looked at the right frame, it would never
see it transition to done and return POLLIN.
The compressed capture code has this same problem, looking in fh->jpg_buffers
when it should have used zr->jpg_buffers.
There was some logic to detect when there was no current capture in process
nor any frames queued and try to return an error, which ends up being a bad
idea. It's possible to call select() from one thread while no capture is in
process, or no frames queued, and then start a capture or queue frames from
another thread.
The buffer state variables are protected by a spin lock, which the code wasn't
acquiring. That is fixed too.

The zr36067 driver doesn't make a distinction between the different sub-types
of NTSC, PAL, or SECAM norms. For example, when the enum std ioctl returns
the PAL standard it returns PAL_BG|PAL_DK|PAL_H|PAL_I.
When setting the norm, it required the bitmask to match exactly the set of
norms used during the enumeration. If just one norm was specified, for
example PAL_BG or NTSC_M, it would fail. This violates the V4L2 spec,
"VIDIOC_S_STD accepts *one* or more flags..."
The key thing to realize is that V4L2_STD_PAL is not one bit, it is multiple
bits. It's ok to call S_STD with any *one* of those bits, but the driver was
requiring *all* of them.
This fixes the S_STD function so that it will accept any set of one or more
PAL norms as PAL, and the same for NTSC and SECAM.

However, that bit was set at the wrong time and could be cleared
by mistake if a PCM (or other) DMA request would arrive before the
VBI DMA was completed. So on completion of the VBI DMA the driver
no longer knew that that DMA transfer was for VBI data. And this
in turn caused havoc with the card's DMA engine.

The bttv driver has code to detect if a tda9887 is present, that was previous
used to auto-load the tda9887 driver. Now there is no tda9887 driver, so the
code is pointless; it just figures out if it should load the driver and then
does nothing.
For cards that are defined as having no tuner, the init code would still do
i2c probes for various tuner devices and auto-load the tuner module. That can
be skipped for cards that don't need it. The code is made to understand that
in addition to 'UNSET', 'TUNER_ABSENT' also means no tuner.
The tuner into printk()s are also made nicer. Levels are added, INFO or
WARNING, depending on the meaning. For cards with no tuner, or no tuner
defined, a more informative message is printed.
Card has no tuner, before patch:
bttv0: tuner type=-1
or
bttv0: tuner type=4
After patch:
bttv0: tuner absent

The last user of dvb_pll_configure was the dvb-usb function
dvb_usb_tuner_calc_regs(), which was nothing more than a wrapper around
dvb_pll_configure(). It's just a copy of the functionality provided by
the tuner_ops calc_regs method, and can be deleted.
There were two users of dvb_usb_tuner_calc_regs().
One was dvb_usb_tuner_set_params_i2c(), which is converted to use
fe->ops.tuner_ops.calc_regs().
The other was the digitv driver. This driver can use one of two demods,
mt352 or nxt6000.
For the mt352, the driver would set tuner_ops.calc_regs to
dvb_usb_tuner_calc_regs().
We can just attach dvb_pll and use the tuner_ops.calc_regs() provided by
that module. For the nxt600, the driver would set tuner_ops.set_params
to digitv_nxt6000_tuner_set_params.
That function would in turn use dvb_usb_tuner_calc_regs().
We convert it to use tuner_ops.calc_regs() instead, and use
dvb_pll_attach.
The digitv_tuner_attach() needs to know which frontend was attached by
digitv_frontend_attach(), since the nxt6000 needs tuner_ops.set_params()
to be overridden with digitv_nxt6000_tuner_set_params().
So, to do this a digitv_state that says which frontend was used is added
to the dvb_usb_device private state field.
