The TMP75C has a different control register layout and only supports
12-bit temperature samples (0.0625 deg C).
The continuous sample rate is ~12 Hz.Signed-off-by: Ben Gardner

Basically it's the same as the original DS75 but much faster.

Most LM75-compatible chips can either sample much faster or with a
much better resolution than the original LM75 chip. So far the lm75
driver did not let the user take benefit of these improvements. Do it
now.I decided to almost always configure the chip to use the best
resolution possible, which also means the longest sample time. The
only chips for which I didn't are the DS75, DS1775 and STDS75, because
they are really too slow in 12-bit mode (1.2 to 1.5 second worst case)
so I went for 11-bit mode as a more reasonable tradeoff. This choice is
dictated by the fact that the hwmon subsystem is meant for system
monitoring, it has never been supposed to be ultra-fast, and as a
matter of fact we do cache the sampled values in almost all drivers.If anyone isn't pleased with these default settings, they can always
introduce a platform data structure or DT support for the lm75. That
being said, it seems nobody ever complained that the driver wouldn't
refresh the value faster than every 1.5 second, and the change made
it faster for all chips even in 12-bit mode, so I don't expect any
complaint.Signed-off-by: Jean Delvare

Explain why clones of the LM75 are generally not detected by the
driver, and why this isn't going to change. Also update the
documentation to reflect the list of chip names currently supported by
the driver.Signed-off-by: Jean Delvare

Add datasheet reference and device ID for ADT75.
The ADT75, like some other LM75 derivatives, needs to be instantiated
using methods 1, 2, or 4.

Part 3: Move the drivers documentation, plus two general documentation
files.Note that the patch "adds trailing whitespace", because it does move the
files as-is, and some files happen to have trailing whitespace.Signed-off-by: Jean Delvare
