There is a specific header sound/ac97_codec.h that defines these.
All drivers should use it instead of rolling its own set of macros.

Reworked device probing to get rid of hacks to guess the maximum size of
dvb iso transfer packets. The new code also selects the first alternate
config which supports the largest possible iso transfers for dvb.

EM28174 is very similar as already supported EM2874.
I am not sure what are differences, but it could be analog support.

Add code enabling the VBI registers for variants of the em28xx chip that
support VBI, and make sure the isoc streaming code continues to work for
the video component of the stream (note the video and vbi data arrive
intermixed on the same isoc pipe).
Note that this version just drops the actual VBI data onto the floor as
opposed to processing it. The "#ifdef 0" tags are for the videobuf code that
appears in the next patch in this series.
We created a separate version of the isoc_copy version for parsing the version
of the stream that includes VBI data. In theory, they might be able to be
merged at some point in the future, but the initial goal is to ensure that we
do not cause any regressions with devices that do not have VBI support.
This work was sponsored by EyeMagnet Limited.

As reported by hermann pitton <hermann-pitton@arcor.de>, some devices
has a different chip id for em2710 (likely the older ones):
em28xx: New device @ 480 Mbps (eb1a:2710, interface 0, class 0)
em28xx #0: Identified as EM2710/EM2750/EM2751 webcam grabber (card=22)
em28xx #0: em28xx chip ID = 17

eeprom configuration.
The em28xx actually has a register that tells the driver what the maximum
packet size is (based on a value programmed into the eeprom). Make use of
that register instead of assuming a hardcoded value of 564 (since 564 is not
correct for devices that do QAM such as the KWorld 340u).
Note that for now the em2874 code isn't there, falling back to the 564 value,
however this is not a problem since there are not any em2874 based devices in
the current v4l-dvb tree).
Thanks to Jarod Wilson for detecting the initial problem and figuring out that
the isoc configuration was wrong for his device.

AC97 devices provide several input and outputs. However, before this
patch, em28xx device weren't properly allowing the usage of ac97
possible combinations. Also, several input volumes were left untouched,
instead of making sure that the volumes were set on mute state.
This patch improves support for ac97 devices by allowing to use any
inputs, and making sure that unused inputs are set on mute state.
Yet, some work is still needed to select the AC97 output.

Refactor the em28xx IR support based on the em2860/em2880 and em2874
datasheets.
Tested on the HVR-950 (em2883), Pinnacle 800e (em2883), Pinnacle 80e (em2874)
using the remote controls that came with those products.

The first em28xx were based on i2c IR's. However, some newer designs
are coming with a polling-based IR. Those are done by reading a register
set at em28xx.
This patch adds core polling support for those devices. Later patches will
add support for some device-specific IR's.
This patch adds the same basic IR polling code used by bttv, cx88 and saa7134, and
shares the common getkey masks defined at ir-common.

Now, all registers will follow the same convension:
EM28XX_R<reg_number>_<reg_name>
This allows to associate a register with its value, and also with a canonical
name. Also, registers that are specific to a given chip were renamed accordingly,
as EM2800_foo (for 2800 only registers) or EM2880_foo (for registers that started
to appear on em2880).
