+ 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).

+ can be displayed full-screen on PAL and a 720x576 video can be
+ displayed without cropping on NTSC.

+ On Screen Display cx23415 Framebuffer driver
+
+ This module presents the cx23415 OSD (onscreen display) framebuffer memory
+ as a standard Linux /dev/fb style framebuffer device. The framebuffer has
+ support for 8, 16 & 32 bpp packed pixel formats with alpha channel. In 16bpp
+ mode, there is a choice of a three color depths (12, 15 or 16 bits), but no
+ local alpha. The colorspace is selectable between rgb & yuv.
+ Depending on the TV standard configured in the ivtv module at load time,
+ the initial resolution is either 640x400 (NTSC) or 640x480 (PAL) at 8bpp.
+ Video timings are locked to ensure a vertical refresh rate of 50Hz (PAL)
+ or 59.94 (NTSC)
