V4L/DVB (5345): ivtv driver for Conexant cx23416/cx23415 MPEG encoder/decoder 

It took three core maintainers, over four years of work, eight new i2c
modules, eleven new V4L2 ioctls, three new DVB video ioctls, a Sliced
VBI API, a new MPEG encoder API, an enhanced DVB video MPEG decoding
API, major YUV/OSD contributions from Ian and John, web/wiki/svn/trac
support from Axel Thimm, (hardware) support from Hauppauge, support and
assistance from the v4l-dvb people and the many, many users of ivtv to
finally make it possible to merge this driver into the kernel.
Thank you all!

This is a video4linux driver for Conexant cx23416 or cx23416 based
PCI personal video recorder devices.
This is used in devices such as the Hauppauge PVR-150/250/350/500
cards.
To compile this driver as a module, choose M here: the
module will be called ivtv.

/*
This file includes an i2c implementation that was reverse engineered
from the Hauppauge windows driver. Older ivtv versions used i2c-algo-bit,
which whilst fine under most circumstances, had trouble with the Zilog
CPU on the PVR-150 which handles IR functions (occasional inability to
communicate with the chip until it was reset) and also with the i2c
bus being completely unreachable when multiple PVR cards were present.
The implementation is very similar to i2c-algo-bit, but there are enough
subtle differences that the two are hard to merge. The general strategy
employed by i2c-algo-bit is to use udelay() to implement the timing
when putting out bits on the scl/sda lines. The general strategy taken
here is to poll the lines for state changes (see ivtv_waitscl and
ivtv_waitsda). In addition there are small delays at various locations
which poll the SCL line 5 times (ivtv_scldelay). I would guess that
since this is memory mapped I/O that the length of those delays is tied
to the PCI bus clock. There is some extra code to do with recovery
and retries. Since it is not known what causes the actual i2c problems
in the first place, the only goal if one was to attempt to use
i2c-algo-bit would be to try to make it follow the same code path.
This would be a lot of work, and I'm also not convinced that it would
provide a generic benefit to i2c-algo-bit. Therefore consider this
an engineering solution -- not pretty, but it works.
Some more general comments about what we are doing:
The i2c bus is a 2 wire serial bus, with clock (SCL) and data (SDA)
lines. To communicate on the bus (as a master, we don't act as a slave),
we first initiate a start condition (ivtv_start). We then write the
address of the device that we want to communicate with, along with a flag
that indicates whether this is a read or a write. The slave then issues
an ACK signal (ivtv_ack), which tells us that it is ready for reading /
writing. We then proceed with reading or writing (ivtv_read/ivtv_write),
and finally issue a stop condition (ivtv_stop) to make the bus available
to other masters.
There is an additional form of transaction where a write may be
immediately followed by a read. In this case, there is no intervening
stop condition. (Only the msp3400 chip uses this method of data transfer).

/* ivtv knows several distinct output modes: MPEG streaming,
YUV streaming, YUV updates through user DMA and the passthrough
mode.
In order to clearly tell the driver that we are in user DMA
YUV mode you need to call IVTV_IOC_DMA_FRAME with y_source == NULL
first (althrough if you don't then the first time
DMA_FRAME is called the mode switch is done automatically).
When you close the file handle the user DMA mode is exited again.
While in one mode, you cannot use another mode (EBUSY is returned).
All this means that if you want to change the YUV interlacing
for the user DMA YUV mode you first need to do call IVTV_IOC_DMA_FRAME
with y_source == NULL before you can set the correct format using
VIDIOC_S_FMT.
Eventually all this should be replaced with a proper V4L2 API,
but for now we have to do it this way. */
