The PCF8591 is plainly impossible to detect! Stupid chip.
So every chip with address in the interval [0x48..0x4f] is
detected as PCF8591. If you have other chips in this address
range, the workaround is to load this module after the one
for your others chips.

On detection (i.e. insmod, modprobe et al.), directories are being
created for each detected PCF8591:

/sys/bus/devices/<0>-<1>/
/sys/bus/i2c/devices/<0>-<1>/
where <0> is the bus the chip was detected on (e. g. i2c-0)
and <1> the chip address ([48..4f])

Inside these directories, there are such files:
in0, in1, in2, in3, out0_enable, out0_output, name
in0_input, in1_input, in2_input, in3_input, out0_enable, out0_output, name

Name contains chip name.

The in0, in1, in2 and in3 files are RO. Reading gives the value of the
corresponding channel. Depending on the current analog inputs configuration,
files in2 and/or in3 do not exist. Values range are from 0 to 255 for single
ended inputs and -128 to +127 for differential inputs (8-bit ADC).
The in0_input, in1_input, in2_input and in3_input files are RO. Reading gives
the value of the corresponding channel. Depending on the current analog inputs
configuration, files in2_input and in3_input may not exist. Values range
from 0 to 255 for single ended inputs and -128 to +127 for differential inputs
(8-bit ADC).

The out0_enable file is RW. Reading gives "1" for analog output enabled and
"0" for analog output disabled. Writing accepts "0" and "1" accordingly.

Description
-----------

This driver implements support for Texas Instruments TMP421, TMP422
and TMP423 temperature sensor chips. These chips implement one local
and up to one (TMP421), up to two (TMP422) or up to three (TMP423)
remote sensors. Temperature is measured in degrees Celsius. The chips
are wired over I2C/SMBus and specified over a temperature range of -40
to +125 degrees Celsius. Resolution for both the local and remote
channels is 0.0625 degree C.

The chips support only temperature measurement. The driver exports
the temperature values via the following sysfs files:

temp[1-4]_input
temp[2-4]_fault
