Yes, our first chip driver is now fully operative. Some parts of it can
still be moved to sensors.o and reused by other drivers, but this can be
done later.
Bug fixes:
* i2c-core.c: Corrected previous patch (a client was now unloaded twice,
which caused problems, as could be expected).
* lm78.c, sensors.c: some minor typos, which caused the crashes
* lm78.c: FAN_DIV only has two fields (fan 3 is not changable)
* sensors.c: ISA/SMBus addresses are prefixed with zeros in directory names

* 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

When you insert i2c-proc.o, you will find some files in /proc/bus (which
is first created for 2.0 kernels). Currently, the following files are
implemented:
* /proc/bus/i2c
A list of i2c/smbus adapters. If DEBUG was true when you compiled this
module, you will also see the ISA pseudo-adapter (if isa.o is loaded).
* /proc/bus/i2c-?
For each adapter in /proc/bus/i2c, a list of registered clients.
If DEBUG was true when you compiled this module, you will also see
the i2c-proc pseudo client.
Of course, these entries are modified when adapters are added/removed.
Kernel 2.1.x users are encouraged to test this module, as /proc entries
are somewhat different beginning with kernel 2.1.29.

* 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?!?

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'.

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!).
