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.

The period handling in saa7134-alsa is broken in two ways. First, the
minimum number of periods of two does not work, because the dma is setup
two periods ahead in the irq handler. Fix the minimum to four periods.
Second, the code assumes that the number of periods is divisible by two,
which isn't always the case on ALSA. Fix by adding a constraint.

The pvrusb2 driver is tearing down its sysfs related pieces in the
incorrect order. This leaves dangling pointers which causes the
kernel device core to oops. The problem has been present virtually
forever but became malignant with the changeover to the way of
handling /sys/class. Fix is just to make sure we don't tear down the
class structure until AFTER the driver instances are deregistered.

This em28xx-video.c uses functions from this header, but doesn't include it.
It depends on some v4l headers included two levels down including poll.h,
which includes mm.h.
These v4l headers might change, so it's best to include the headers needed
directly.
It also causes problems for the out of core build system's backward
compatibility with older kernels, which is the real reason I bothered to
create a patch for something that would otherwise be so minor that it would
hardly be worth the trouble.

You are right. The patch below (based on your cx88 patch, but I don't
really understand it) fixes mmap support in saa7134-alsa for me.
Recording via mmap (arecord -M -f S16_LE -c 2 -r 32000 -D hw:1) didn't
work at all before, works now, tested for at least 20 minutes (but,
unfortunately, with one overrun at least 0.719 ms long).

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.
