Depending on the model there are three different firmwares to choose from.
Unfortunately if a cx23885 is loaded first, then the global firmware name
is overwritten with that firmware and if ivtv is loaded next, then it
tries to load the wrong firmware. In addition, the original approach would
also overwrite any firmware that the user specified explicitly.

After the i2c subdev changes the ordering of initialization changed,
causing a total loss of previous GPIO settings and a loss of DTV.
The generic firmware loading routine has now changed to preserve
GPIO values if the device is cx23885 based (safety) and I've
moved the GPIO configuration from probe() into the cx23885 init
func which is a little clearer and fixes the bug.

It is no longer needed to use a struct pointer as argument, since v4l2_subdev
doesn't require that ioctl-like approach anymore. Instead just pass the input,
output and config (new!) arguments directly.

Originally the intention was to switch to the new style i2c API starting with
the introduction of the API in 2.6.22. However, the i2c_new_probed_device()
function has a lethal bug that wasn't fixed until 2.6.25. Or more accurately,
it was only fixed in the stable series of 2.6.25 and 2.6.26.
Given the fact that the new i2c API also changed starting with 2.6.26 (the
addition of i2c_device_id), it is easiest to switch APIs starting with
2.6.26.
This patch updates all the legacy code accordingly.

s_std didn't belong in the tuner ops. Stricly speaking it should be part of
the video ops, but it is used by audio and tuner devices as well, so it is
more efficient to make it part of the core ops.

The init callback was used in several places to load firmware. Make a separate
load_fw callback for that. This makes the code a lot more understandable.

The audio and vbi functions where still called through an ioctl-like

The v4l2_ctrl_query_fill_std() function wasn't one the best idea I ever had.
It doesn't add anything valuable that cannot be expressed equally well with
v4l2_ctrl_query_fill and only adds overhead.
Replace it with v4l2_ctrl_query_fill() everywhere it is used and remove it
from v4l2_common.c.

These days TUNER_SET_CONFIG is broadcast to the other i2c devices
and that triggers a fw load on the cx25840. Ignore this command
since cx25840 isn't a tuner and you really do not want to load
the firmware that early.

With the conversion to v4l2_subdev one bit of code was accidentally dropped:
on receiving the first command the driver has to load the fw. A new init()
command was introduced to do that explicitly for bridge drivers that are
converted to use v4l2_subdev, but old drivers that are not yet converted
no longer worked.
This patch fixes this regression for these old drivers.

The change that introduced it follows. The first part of the change,
with the 2 "static"s is the problem. The second part of the change,
for
older kernels is correct. Remove the duplicate static keyword and the

Since the i2c driver ID will be removed in the near future we have to
modify the v4l2 debugging API to use the driver name instead of driver ID.
Note that this API is not used in applications other than v4l2-dbg.cpp
as it is for debugging and testing only.
Should anyone use the old VIDIOC_G_CHIP_IDENT, then this will be logged
with a warning that it is deprecated and will be removed in 2.6.30.

The service_set field was used in saa7115 and cx25840 to determine
whether raw or sliced VBI was desired. This is incorrect since it is
perfectly valid to select sliced VBI with a service_set of 0.
Instead these drivers should checked on VIDIOC_S_FMT whether the type
field matches the raw or sliced VBI type.
Updated ivtv accordingly.

Since:
1) FW_LOADER is defined as:
config FW_LOADER
tristate "Userspace firmware loading support"
depends on HOTPLUG
2) several V4L/DVB driver just selects it;
3) select is not smart enough to auto-select HOTPLUG, if select FW_LOADER.
So, All drivers that select FW_LOADER should also depend on HOTPLUG.
An easier solution (for the end-user perspective) would be to "select HOTPLUG".
However, live is not simple. This would cause recursive dependency issues like
this one:
drivers/usb/Kconfig:62:error: found recursive dependency: USB -> USB_OHCI_HCD
-> I2C -> MEDIA_TUNER -> MEDIA_TUNER_XC2028 -> HOTPLUG -> PCCARD -> PCMCIA ->

Audio muting for the tuner input was implemented by stopping the audio
microcontroller and restarting it on unmute. However, it appears that this
method can actually crash the audio firmware. It's rare and seems to
happen with NTSC only.
It has been reimplemented by setting to volume to 0. In addition, the
reporting of the mute state has been improved as well: it used to be
impossible to detect whether the audio was muted by the user or if it
was muted due to the microcontroller trying to detect the audio
standard. This is now clearly stated.
