Previously, all yuv data written to /dev/video48 had only basic support with
no double buffering to avoid display tearing.
With this patch, yuv frames written to video48 are now handled by the existing
IVTV_IOC_DMA_FRAME framework. As such, the frames are hardware buffered to
avoid tearing, and honour scaling mode & field order options. Unlike the
proprietary IVTV_IOC_DMA_FRAME ioctl, all parameters are controlled by the
V4L2 API.
Due to mpeg & yuv output restrictions being different, their V4L2 output
controls have been separated. To control the yuv output, the V4L2 calls must
be done via video48.
If the ivtvfb module is loaded, there will be one side effect to this merge.
The yuv output window will be constrained to the visible framebuffer area. In
the event that a virtual framebuffer size is being used, the limit to the
output size will be the virtual dimensions, but only the portion that falls
within the currently visible area of the framebuffer will be shown.
Like the IVTV_IOC_DMA_FRAME ioctl, the supplied frames must be padded to 720
pixels wide. However the height must only be padded up the nearest multiple
of 32. This would mean an image of 102 lines must be padded to 128. As long
as the true source image size is given, the padding will not be visible in
the final output.

Interlace mode selection code moved into the frame setup phase, so it's now
run before the frame is loaded into a hardware buffer. Given that it can
affect how a new frame is displayed, it was a bit stupid running it after the
frame was already visible.
A few stray interlace related variables which were linked to individual frames
have now been moved into the yuv_frame_info struct. This means that all
variables linked to a specific frame are in the same place & not scattered.

To reduce the number of display register accesses, the yuv code keeps track of
the current video settings. Should there be a change in any single parameter,
it will update the associated display registers to ensure everything is
displayed correctly.
The existing check also looks at the field order for the video. This is not
required, since field reversal does not require any display register changes.

Currently the yuv output stream buffer is divided into blocks whose size
depend on the broadcast standard selected during the driver init phase.
However, the standard can be changed after the init phase. This effectively
breaks the yuv output stream handler, since it relies on the different yuv
planes being block aligned.
This patch changes the setup, so that the block size is always the same. The
decoder dma function has been modified to cope with the fact that the second
yuv plane may no longer be block aligned. The start of the yuv frame must
still be at the beginning of a block, so the stream write function has also
been modified to ensure this is always true.
Also, the stream write function will now initiate a yuv dma transfer as soon
as a full frame is ready. It will not wait until the current write request
has completed, or the stream buffer becomes full.

The exact routing of video and audio signals within a device is a
device-specific attribute. Hauppauge devices do it one way; other
types of device may route things differently. Unfortunately it is
rather impractical to define chip-specific routing at the device
attribute level, so instead what happens here is that "schemes" are
defined. Each chip level interface implements its part of a given
scheme and the scheme as a whole is made into a device specific
attribute controlled via a table entry in pvrusb2-devattr.c. The only
scheme defined here is for Hauppauge devices, but clearly this opens
the door for other possibilities to follow.

This is a new implementation for video pipeline control within the

driver's kernel thread. Pipeline stages are controlled autonomously
based on surrounding pipeline or application control state. Kernel
thread management is also cleaned up and moved into the internal
control structure of the driver, solving a set up / tear down race
along the way. Better failure recovery is implemented with this new
control strategy. Also with this change comes better control of the
cx23416 encoder, building on additional information learned about the
peculiarities of controlling this part (this information was the
original trigger for this rework). With this change, overall encoder
stability should be considerably improved. Yes, this is a large
change for this driver, but due to the nature of the feature being

Define a list of valid "firmware types" for each combination of BASE,

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

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.

Any i2c read request that was not immediately preceded by a write request was
incorrectly taking the write path. Add the capability to handle individual
read requests.

Callers to cxusb_ctrl_msg currently do not receive any indication that their
transfer failed. Return the true return code from dvb_usb_generic_{rw,write}.

The saa7134-oss is deprecated for quite some time, it's the only remaining OSS
user outside of sound/oss/, and considering how few and what kind of
soundcards are left supported by OSS I hardly see any use cases left.

The ability to read Hauppauge eeprom's was recently added to saa7134,
so we must build the tveeprom module.
Thanks to Matthias Schwarzott for pointing this out.

The HVR-900 requires the MTS version of the xc3028 firmware in order
to get any sound. The below patch selects this firmware variant on
HVR-900 cards, as well as splitting the HVR-950 into its own entry
(since I don't know if it uses the MTS variant and it will have to be
split off eventually anyway).

Increased size of dev->eedata from 128 to 256, since the Hauppauge data begins
at byte 128. This has been tested on boards with smaller eeproms, and caused
no problems.
Added comments to distinguish between the various versions of the HVR1110.
