V4L/DVB (9657): em28xx: add a functio to write on a single register
Introduce a new function that writes to a single register. This is
useful because the vast majority of register writes are a single
register, and this format permits or'ing register value bits together.
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.
V4L/DVB (9652): em28xx: merge AC97 vendor id's into a single var
This makes easier to identify vendor ID, since AC97 vendors are
generally identified by 3 bytes. The remaining byte is used by the
vendor to identify its devices.
This patch properly implements audio handling on em28xx. Before this
patch, it was assumed that every device has an Empia 202 audio chip.
However, this is not true.
After this patch, specific AC97 chipset setup and configurations can be
done.
V4L/DVB (9643): em28xx: remove the previous register names
Previously, AC97 registers were named as if they were part of em28xx
device, generating some confusion. Replace such names for a more general
naming convention.

V4L/DVB (9633): Put s5h1411 into low power mode at end of attach() call
Place the s5h1411 into low power mode until first use (to handle the case where
the user plugs in the device and then doesn't use it for a while). On the
Pinnacle 801e, this brings the power usage from 126ma down to 82ma.
V4L/DVB (9607): em28xx: Properly implement poll support for IR's
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.
V4L/DVB (9590): Add registration for Pinnacle 80e ATSC tuner
Add registration for Pinnacle 80e ATSC tuner

Thanks to Joerg Schindler from Pinnacle for providing sample hardware.
Thanks to Rainer Miethling from Pinnacle for providing engineering support.
V4L/DVB (9585): Skip reading eeprom in newer Empia devices
Empia switched to a 16-bit addressable eeprom in newer devices. While we
could certainly write a routine to read the eeprom, there is nothing of use
in there that cannot be accessed through registers, and there is the risk that
we could corrupt the eeprom (since a 16-bit read call is interpreted as a
write call by 8-bit eeproms). So just be safe and bail out of the function.
Thanks for Ray Lu from Empia for providing the em2874 datasheet.
V4L/DVB (9584): Support different GPIO/GPO registers for newer devices
Empia moved the location of the GPIO/GPO registers in newer devices. Add the
ability to specify the relocated registers (including caching of register
contents).
Thanks for Ray Lu from Empia for providing the em2874 datasheet.
V4L/DVB (9570): uvcvideo: Handle failed video GET_{MIN|MAX|DEF} requests more gracefully
Failed requests will now generate a one-time warning message instead of the
usual "Failed to query..." error, which should be more user-friendly. The
driver will also recover automatically from failed GET_MIN/GET_MAX requests
when the device is half-broken without requiring the MINMAX quirk (fully
broken devices still need the quirk).

V4L/DVB (9569): uvcvideo: Sort the frame descriptors during parsing
The UVC specification does not require frame descriptors to be sorted by
bFrameIndex. At least one camera (145f:013e) is known not to sort the
descriptors properly, so they need to be sorted during parsing as the driver
then accesses them by index.

- radio tuner
- composite 1 & 2 (only 1 is physically available, but composite 2 is also

This patch is part of a larger patch series which will remove
the "char bus_id[20]" name string from struct device. The device
name is managed in the kobject anyway, and without any size
limitation, and just needlessly copied into "struct device".
To set and read the device name dev_name(dev) and dev_set_name(dev)
must be used. If your code uses static kobjects, which it shouldn't
do, "const char *init_name" can be used to statically provide the
name the registered device should have. At registration time, the
init_name field is cleared, to enforce the use of dev_name(dev) to
access the device name at a later time.
We need to get rid of all occurrences of bus_id in the entire tree
to be able to enable the new interface. Please apply this patch,
and possibly convert any remaining remaining occurrences of bus_id.
We want to submit a patch to -next, which will remove bus_id from
"struct device", to find the remaining pieces to convert, and finally
switch over to the new api, which will remove the 20 bytes array
and does no longer have a size limitation.
