The MAX6874/MAX6875 ignores address bit 0, so this driver attaches to multiple
addresses. For example, for address 0x50, it also reserves 0x51.
The even-address instance is called 'max6875', the odd one is 'max6875 subclient'.
The even-address instance is called 'max6875', the odd one is 'dummy'.

Detection
---------
The PCA9539 is difficult to detect and not commonly found in PC machines,
so you have to pass the I2C bus and address of the installed PCA9539
devices explicitly to the driver at load time via the force=... parameter.

Accessing PCF8574(A) via /sys interface
-------------------------------------
! Be careful !
The PCF8574(A) is plainly impossible to detect ! Stupid chip.
So every chip with address in the interval [20..27] and [38..3f] are
detected as PCF8574(A). If you have other chips in this address
range, the workaround is to load this module after the one
for your others chips.
So, you have to pass the I2C bus and address of the installed PCF857A
and PCF8574A devices explicitly to the driver at load time via the
force=... parameter.
On detection (i.e. insmod, modprobe et al.), directories are being
created for each detected PCF8574(A):

---------
There is no method known to detect whether a chip on a given I2C address is
a PCF8575 or whether it is any other I2C device. So there are two alternatives
to let the driver find the installed PCF8575 devices:
- Load this driver after any other I2C driver for I2C devices with addresses
in the range 0x20 .. 0x27.
- Pass the I2C bus and address of the installed PCF8575 devices explicitly to
the driver at load time via the probe=... or force=... parameters.
