basically an expanded LM75. It can have an external temp probe (in
addition to the internal one), customizable conversion rate (in # of times
per second, depending on power consumption requirements), and
actually has a device-id register for easier/more-certain detecting!
The only strange property is the low-limit. The low-limit doesn't act
as a Hystersis value like the LM75. I.e., if the temp falls below it,
it triggers an alarm instead of clearing it. Strange, ey? This makes
using the chip for a thermostat control (like for a fan) much harder.
But it *could* be used to turn on a heater to prevent your computer from
freezing. :')
Here's what my output looks like (without a remote sensor. temp's
are the same format as the LM75 [high-limit, low-limit, value]):

PS- all temp values in the ADM1021 (limits and readings) are signed
(2's comp) bytes. So, all readings go from -128 to 127 C (actually,
the docs say it can only reliable sense down to -65), and only
in whole degree increments.

* Added lib directory; the library will live here
* Added Makefile fragment in the lib dir
* Modified README.directories to include the new dir
* Added lib directory to the fragments the Makefile uses

has no Winbond specific features implemented yet. Proper testing for
a Winbond also needs to be implemented. src/Module.mk and src/sensors.h
were modified slightly to support the new driver.

To be done: support for GL518SM revision 0x80 and GL520SM
Kyösti, if you have some time soon, could you please test it?

Yet more documentation updates, and a quick Makefile update to install all
include files correctly.
git-svn-id: http://lm-sensors.org/svn/lm-sensors/trunk@50 7894878c-1315-0410-8ee3-d5d059ff63e0
* Header files isa.h, sensors.h and smbus.h will now be installed on a
'make install';
* #ifdef __KERNEL__ added to the above header files where appropriate;
* Correct files are included, both if __KERNEL__ is true and false.

Well, it should work. But until we have implemented the remaining parts of
piix4.o, we won't be able to test it. Anybody?
git-svn-id: http://lm-sensors.org/svn/lm-sensors/trunk@29 7894878c-1315-0410-8ee3-d5d059ff63e0
* Some Makefile changes. doc/makefiles documents most of them.
* The lm78 module now compiles, but it will still crash.
* New module sensors, with general code usable by chip driver modules
* i2c-core: added function i2c_adapter_id(), which returns a (low)
unique i2c-bus ID.
* lm78.h stuff moved into lm78.c or sensors.h
git-svn-id: http://lm-sensors.org/svn/lm-sensors/trunk@19 7894878c-1315-0410-8ee3-d5d059ff63e0
* i2c-bus is renamed to i2c-proc
* small patch in i2c-core.c (see correspondence with Simon Vogl)
* sensors.h contains i2c constants
* It seems lm78.[ch] was not yet committed?!?
git-svn-id: http://lm-sensors.org/svn/lm-sensors/trunk@16 7894878c-1315-0410-8ee3-d5d059ff63e0
Nothing much here yet, except some code to create /proc/bus/i2c. Should work
for kernels 2.0 and 2.1 (please test).
Other notable things:
printk statements in all modules made to have to same 'look'.
git-svn-id: http://lm-sensors.org/svn/lm-sensors/trunk@15 7894878c-1315-0410-8ee3-d5d059ff63e0
Though it is called the LM78 driver, there is not too much LM78 specific
code in it; it can better be seen as an example code skeleton for other
drivers. Right now, it creats a file /proc/sensors-test, which contains
a list of busses it registered itself on. Stupid, but very useful for
testing purposes!
You need a 2.0 kernel for lm78.o to insert (or hack the /proc system
specific parts; see lm78.c of lm_sensors version 1 how to do this).
Other parts of lm_sensors-2 are not tested for 2.1 kernels either, but
I am certain it won't work in this case :-).
See the TODO list to get some idea what is left to do, choose something
and implement it. Or not :-). But please, send a note to the mailing
list when you start on something, to avoid duplicate work...
Other notable changes:
the smbus_access routines now use (the more logical) i2c_adapter
structure, instead of smbus_adapter.

* Modules now print their version number and date on insertion
* Some printk statements missed a \n
* 'make clean' now works, even if some .d (dependency) files contain garbage.
Note that *only* 'make clean' helps in that case; 'make clean all', for
example, will fail! There is really no nice way to solve that.

The real PIIX4 access code must still be written; perhaps somebody else could
do this? Most of it could be copied from the old piix4.c. But check carefully
what you are doing, as some things *have* changed (like the SMBUS_{BYTE,...}
variables!).
