Detection is completely impossible, but sensors-detect now assumes with a
confidence of 1 (the lowest possible) that any chip in the LTC1710 address
range is a real LTC1710. Perhaps I should remove this again, as I don't
think this chip will be encountered 'in the wild' if your name is not Phil -
in which case you would have soldered it to your SMBus yourself, so you
should know what you are doing...

device drivers. Specifically, I added these lines:
(in includes list)
#include "i2c-isa.h"
(Near beginning of *-attach-adapter function)
/* Make sure we aren't probing the ISA bus!! */
if (i2c_is_isa_adapter(adapter)) return 0;
This may be redundant is a couple of the files, but it shouldn't hurt.

All our own code (ie. anything not in the i2c directory) compiles now without
warnings, even with WARN=1 (which sets -Wall -Wstrict-prototypes -Wshadow
-Wpointer-arith -Wcast-qual -Wcast-align -Wwrite-strings -Wnested-externs
-Winline). There is one exception: the lex code (conf-lex.l) complains about
unused functions. That's flex' fault, not ours!
The i2c code still emits many warnings with the above flags; that's Simon's
problem.

switch. It can switch two devices which each consume 300mA at 5V (or less).
This is good for fans, lights, or into relays for heftier stuff.
Here's what the usage looks like:
[root@penn sensors]# ls ltc1710-i2c-1-58/*
ltc1710-i2c-1-58/switch1
ltc1710-i2c-1-58/switch2
[root@penn sensors]# cat ltc1710-i2c-1-58/*
0
0
[root@penn sensors]# echo "1" > ltc1710-i2c-1-58/switch2
(blue LED turned on)
[root@penn sensors]# cat ltc1710-i2c-1-58/*
0
1
One problem with the device: It doesn't support reads. It ignores any
read transactions, so even detection with a read won't work. This
also means that the status of the switches has to be remembered and
can't be polled.
As simple as this device is, it is one of the few which actually
allows the computer to send signals OUT into the world to
control something.
