05b2723387 V4L/DVB (6083): cx88-alsa: Rework buffer handling
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.

19453bc188 V4L/DVB (6068): cx88-alsa: Use pci_dev->revision
The revision is part of the pci_dev struct, so there is no need to read it in.

Stop storing the revision and latency in the chip struct, since they're never
used after being printed out when the driver loads.

linux/pci.h wasn't included.  It was getting picked up something else,
probably cx88.h, but this file uses struct pci_dev so it should include pci.h.

59fd8f8d8e V4L/DVB (6066): cx88-alsa: Change order of interrupt enabling, fix spurious IRQs
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.

fa40b2237a V4L/DVB (6034): cx88: Add parameter to control radio deemphasis time constant
FM radio transmission use a preemphasis/deemphasis scheme to reduce
high-frequency noise.  The cx88 audio decoder is supposedly set to no
deemphasis by the current driver.

However, the "no deemphasis" setting doesn't work.  On my chip, cx23883, it
produces the same result as the 75 us time constant.  Maybe the default
settings on the cx23881 are for 50 us?

Since the deemphasis time constant varies by country, allow setting it via a
module parameter.

5772f81326 V4L/DVB (6023): cx88: Clean up some ugly and inconsistent printk()s
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.

Also fix some ugly printks in the cx8802 driver that used __FUNCTION__ for
KERN_INFO and KERN_ERR messages.

The changed printks in cx88-mpeg.c also needed lots of whitespace and
80-column fixes.

A bunch of misc changes in cx88-dvb.c and cx88-video.c to add message levels
or a consistent "cx88[?]/2" or "cx88[?]/0" prefix.

bbc83597df V4L/DVB (6022): cx88: Move card core creation from cx88-core.c to cx88-cards.c
A lot of code in cx88-cards.c was only used by cx88-core.c when the core state
is first allocated and initialized.  Moving that task to cx88-cards makes the
driver simpler and the files more self contained.

- Module parameters tuner, radio, card, and latency move to cx88-cards.c
- cx88_boards is made static
- cx88_subids is made static and const
- cx88_bcount is eliminated
- cx88_idcount is eliminated
- cx88_card_list() is made static
- cx88_card_setup_pre_i2c() is made static
- cx88_card_setup() is made static
- cx88_pci_quirks() is moved from cx88-core to cx88-cards
  The function argument "char *name" is made const too
- get_ressources() is moved from cx88-core to cx88-cards, and renamed to
  cx88_get_resources()
- The code to allocate and initialize the core state struct and the chip is
  moved out of cx88-core.c:cx88_get_core() and into a new function in
  cx88-cards.c, cx88_core_create().  This makes both functions simpler.

6a59d64c5c V4L/DVB (6021): cx88: Copy board information into card state
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.

19dc74b7c5 V4L/DVB (5975): cx88: Wrong values used for HD-3000 radio mode
After some tedious work with a logic probe and a magnifying glass, I've
determined that GPIO 7 is used to switch between the DTT7612's Sound 4.5 MHz
IF output on pin 12 and the FM 10.7MHz If output on pin 11.  GPIO 2 is used to
switch the card's analog sound output from from the analog input connector to
the CX23883's audio DACs.

So, in radio mode GPIO2 = 1 and GPIO7 = 0.

Add some comments about how the HD-3000's GPIOs are connected.

Delete the vmux setting for the radio, as vmux doesn't apply to radio mode.
Also delete the lines setting unused gpio words to zero; it's not necessary as
0 is the default value for uninitialized fields.

b7754d74d2 V4L/DVB (5636): Integrate all users of the fmd1216 tuner with dvb-pll
Enhance the dvb-pll definition of the fmd1216 tuner by adding an init sequence
and a sleep sequence.

The init sequence sets the AGC control register to 0xa0, selecting the fast
time constant and 112 dBuV take-over point.  This the recommended value for
DVB-T operation.

The sleep sequence sets bit P4 (which is believed to turn the analog
demodulator on), turns off the tuning voltage, and sets the AGC control
register to 0x60 (external AGC voltage, the recommended value for analog
operation).

The existing dvb-pll users in the cx88 driver, listed below, will gain these
init and sleep sequences.

user is removed.

SAA7134_BOARD_ASUS_EUROPA2_HYBRID       Asus Europa2 OEM

The saa7134 functions philips_fmd1216_tuner_init(),
philips_fmd1216_tuner_sleep(), and philips_fmd1216_tuner_set_params() are
deleted and the dvb-pll versions are used.

This should result in equivalent sleep, init, and tuning sequences being sent
to the tuner.

For the cxusb driver, only one board is effected:

USB_PID_MEDION_MD95700          	Medion MD95700

This board used dvb_usb_tuner_init_i2c() and dvb_usb_tuner_set_params_i2c()
for init and tuning, respectively.  These functions are effectively the same
as the dvb-pll versions.  They call a tuner pass control function defined at
the dvb-usb level, but this does not matter, as this card does not have a
tuner pass control function (only the dib3000mb does).  This board will gain
the sleep sequence, while init and tuning should be unchanged.

4abe9f9d94 V4L/DVB (5633): Tuv1236d: move rf input switching code into dvb-pll
This patch removes duplicate code from cx88-dvb and saa7134-dvb that handles
rf input switching for the TUV1236d tuner.

The functionality is added to dvb-pll, where all the other code that 
handles the TUV1236d is kept.

Rename dvb_pll_desc.setbw() to set(), and accept struct dvb_frontend_parameters
instead of passing both freq and bandwidth, so that this may be used as a
generic function.

In order to do this, dvb_pll_configure must also be altered in the same manner,
to take struct dvb_frontend_parameters instead of freq and bandwidth.

ecf854df72 V4L/DVB (5629): Cx88: VP3054 support can't be a module when cx88 is compiled in
If cx88 support is compiled into the kernel while vp3054 is left as a module,
the kernel will fail to link.  Adjust the existing "#if" code in cx88 so
that it won't consider vp3054 to be supported in this case.

It might make sense to move vp3054 selection into the "customisation" menu
instead of a cx88 sub-option (though this is a cx88 feature, there is no extra
chip involved).

It might also make sense to use dvb_attach() to load vp3054 support.

8314418629 Freezer: make kernel threads nonfreezable by default
Currently, the freezer treats all tasks as freezable, except for the kernel
threads that explicitly set the PF_NOFREEZE flag for themselves.  This
approach is problematic, since it requires every kernel thread to either
set PF_NOFREEZE explicitly, or call try_to_freeze(), even if it doesn't
care for the freezing of tasks at all.

It seems better to only require the kernel threads that want to or need to
be frozen to use some freezer-related code and to remove any
freezer-related code from the other (nonfreezable) kernel threads, which is
done in this patch.

The patch causes all kernel threads to be nonfreezable by default (ie.  to
have PF_NOFREEZE set by default) and introduces the set_freezable()
function that should be called by the freezable kernel threads in order to
unset PF_NOFREEZE.  It also makes all of the currently freezable kernel
threads call set_freezable(), so it shouldn't cause any (intentional)
change of behaviour to appear.  Additionally, it updates documentation to
describe the freezing of tasks more accurately.

f057131fb6 V4L/DVB (5816): Cx88-blackbird: fix vidioc_g_tuner never ending list of tuners
v4l-info and other programs would loop indefinitely while querying the
tuners for cx88-blackbird cards.

The cause was that vidioc_g_tuner didn't return an error value for
qctrl->id != 0, making the application think there is a never ending
list of tuners...

This patch adds the same index check as done in vidioc_g_tuner() in
cx88-video.

6473d160b4 PCI: Cleanup the includes of <linux/pci.h>
I noticed that many source files include <linux/pci.h> while they do
not appear to need it. Here is an attempt to clean it all up.

In order to find all possibly affected files, I searched for all
files including <linux/pci.h> but without any other occurence of "pci"
or "PCI". I removed the include statement from all of these, then I
compiled an allmodconfig kernel on both i386 and x86_64 and fixed the
false positives manually.

My tests covered 66% of the affected files, so there could be false
positives remaining. Untested files are:

arch/alpha/kernel/err_common.c
arch/alpha/kernel/err_ev6.c
arch/alpha/kernel/err_ev7.c

I would welcome test reports for these files. I am fine with removing
the untested files from the patch if the general opinion is that these
changes aren't safe. The tested part would still be nice to have.
