V4L/DVB (6184): cx88-alsa: Make volume control stereo
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.

V4L/DVB (6126): tuner: add warning for obsolete i2c address range 0x64 thru 0x6f
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:
====================== WARNING! ======================
Support for tuners in i2c address range 0x64 thru 0x6f

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.
