+	  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).
