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!

19 This is a video4linux driver for Conexant cx23416 or cx23416 based
20 PCI personal video recorder devices.
21
22 This is used in devices such as the Hauppauge PVR-150/250/350/500
23 cards.
24
25 To compile this driver as a module, choose M here: the
26 module will be called ivtv.

22 This file includes an i2c implementation that was reverse engineered
23 from the Hauppauge windows driver. Older ivtv versions used i2c-algo-bit,
24 which whilst fine under most circumstances, had trouble with the Zilog
25 CPU on the PVR-150 which handles IR functions (occasional inability to
26 communicate with the chip until it was reset) and also with the i2c
27 bus being completely unreachable when multiple PVR cards were present.
28
29 The implementation is very similar to i2c-algo-bit, but there are enough
30 subtle differences that the two are hard to merge. The general strategy
31 employed by i2c-algo-bit is to use udelay() to implement the timing
32 when putting out bits on the scl/sda lines. The general strategy taken
33 here is to poll the lines for state changes (see ivtv_waitscl and
34 ivtv_waitsda). In addition there are small delays at various locations
35 which poll the SCL line 5 times (ivtv_scldelay). I would guess that
36 since this is memory mapped I/O that the length of those delays is tied
37 to the PCI bus clock. There is some extra code to do with recovery
38 and retries. Since it is not known what causes the actual i2c problems
39 in the first place, the only goal if one was to attempt to use
40 i2c-algo-bit would be to try to make it follow the same code path.
41 This would be a lot of work, and I'm also not convinced that it would
42 provide a generic benefit to i2c-algo-bit. Therefore consider this
43 an engineering solution -- not pretty, but it works.
44
45 Some more general comments about what we are doing:
46
47 The i2c bus is a 2 wire serial bus, with clock (SCL) and data (SDA)
48 lines. To communicate on the bus (as a master, we don't act as a slave),
49 we first initiate a start condition (ivtv_start). We then write the
50 address of the device that we want to communicate with, along with a flag
51 that indicates whether this is a read or a write. The slave then issues
52 an ACK signal (ivtv_ack), which tells us that it is ready for reading /
53 writing. We then proceed with reading or writing (ivtv_read/ivtv_write),
54 and finally issue a stop condition (ivtv_stop) to make the bus available
55 to other masters.
56
57 There is an additional form of transaction where a write may be
58 immediately followed by a read. In this case, there is no intervening
59 stop condition. (Only the msp3400 chip uses this method of data transfer).
