In practice, the tuner occasionally fails to respond correctly after a
firmware load. Retry the firmware load if the firmware/hardware version
we read back from the tuner after programming does not match what we
expect.

Define a list of valid "firmware types" for each combination of BASE,
DTV and SCODEs. By masking the appropriate firmware bits off we can
just use one "type" for the firmware searching and also flag when we
are looking for a BASE, DTV or SCODE type firmware. This makes it
much easier to track if we need to change device modes or flash an
individual firmware part.
Add a structure to remember what firmware properties we have. This
contains the currently loaded/wanted base firmware (type), video std
(id), video std requested (std_req), scode file and number in use.
Incorporate said structure into the tuner private data.
When checking whether the current firmware needs to be reloaded, first
figure out exactly what "type" of firmware we want (base, std and
scode), and then proceed to load the appropriate matching base,
std-specific and scode records iff there are any changes required.
This removes guesswork from the process because we no longer need to
individually code a check for every tuning parameter's interactions.

Rather than picking the first video standard firmware that supports any of
the standards that the user has requested, try to select one that supports
as many of them as possible. This improves the likelihood that the firmware
we select will support the user's desired TV standard.

There is no need to duplicate the max_len field from the ctrl structure
in the private data. If we use it directly from priv->ctrl, we can memcpy
the structure (apart from strings) to reduce maintenance as it grows.
Enforce a minimum max_len length of 8 data bytes (+ 1 address byte) as seems
to be required by the tuner.
Also, use kstrdup instead of open coding the string duplication.

The V4L1 spec says that the image size should be with with VIDIOCSWIN before
requesting buffers with VIDIOCGMBUF and capturing into them with
VIDIOCMCAPTURE.
But it seems that many apps don't do this. They set the size using the fields
in the VIDIOCMCAPTURE ioctl. The driver doesn't know what size to capture
until it actually starts to capture. In particular, it doesn't know what size
to capture until it has already mmap the captured buffers. Which is quite
stupid. Why V4L1 has size and format fields for VIDIOCMCAPTURE I have no idea.
Many drivers don't support this, including those using v4l1-compat.
The bttv does, which is probably the only reason such broken software is so
prevalent.
But, the driver doesn't adjust its idea of what size is being captured when it
is set this way. If you try to query the driver's current setting with
v4l2-ctl, it won't be correct.

The bttv driver instists that the depth specified in the call to VIDIOCSPICT
match the pixel format specified in the same call.
vlc doesn't set the depth field, which makes the SPICT ioctl always fail.
The V4L1 standard is not clear on how most operation are supposed to work, and
this is no exception. The depth field would appear to be entirely redundant,
as the pixel format specifies a specific depth. It could be that this field
was only meant for output from the *G*PICT ioctl and should be ignored in
*S*PICT. This is in fact what the v4l1-compat wrapper does.

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.

From: Mauro Carvalho Chehab <mchehab@infradead.org>
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.

Driver core: change add_uevent_var to use a struct
This changes the uevent buffer functions to use a struct instead of a
long list of parameters. It does no longer require the caller to do the
proper buffer termination and size accounting, which is currently wrong
in some places. It fixes a known bug where parts of the uevent
environment are overwritten because of wrong index calculations.
Many thanks to Mathieu Desnoyers for finding bugs and improving the
error handling.

When the ivtvfb module is loaded, the YUV output is relative to the
framebuffer output. When a virtual screen size is used, the output area for
the YUV may actually be off screen. To prevent the hardware from crashing,
the current driver will ignore an off-screen position and leave the output
visible at the last on-screen position. This may not be desirable, so this
patch will switch off the YUV output should the image move off-screen, and
re-enable it should the image move on-screen again.
