* True SMBus host support for VIA southbridges
Supports PCI devices:
1106:3050 VT82C596 "Via Apollo Pro / Pro+"
1106:3057 VT82C686 "Via Apollo MVP4"
I have no hardware to test these..

* Fixed adapter drivers to compile with the new i2c structs.
They might, or they might not work..

* The i2c package can no longer be compiled as part of the lm_sensors tree
* The archive of the i2c package is removed
* smbus, i2c-dev and i2c-proc modules and headers have been removed; they
are now completely integrated into the i2c package
* The fake i2c.h header has been removed; this also allowed us to remove
the ugly LM_SENSORS and TBD defines.
* A new variable I2C_HEADERS is introduced in the Makefile. This allows
us to install the i2c headers in, for example, /usr/local/include/linux.
* All files now include <linux/i2c.h> instead of "i2c.h" and "smbus.h"
Status: 'make dep' works, all the right include files are found. 'make all'
does not yet work.

* Made i2c-voodoo3.c compile with 2.0 kernels
It should also run without problem, but obviously I could not test it
Changes are in the memory mapping of PCI address space
* Removed several warning from i2c-voodoo3.c
It compiles now without any warnings, even with WARN=1
* Removed several warnings from matorb.c
It compiles now without any warnings, even with WARN=1
In the proces, I fixed one serious bug (assignment instead of comparison)
* Removed a warning from w83781d.c
It compiles now without any warnings, even with WARN=1
Hint: Once in a while, try to compile with WARN=1 and remove warnings. It
helps to find serious, hidden problems. Really!

bad like 'oops' when there is more than one voodoo3 in the system or when
there is none.

during a transaction. It also can detect a 'hung' bus prior to starting
a transaction. It seems to properly read and write to the BT869.
Todo: support for multiple voodoo3 cards. Support for other transaction
types (fairly simple). Use code as a start for a better algo-bit
adapter template? Complete the bt869 driver.

Voodoo3 I2C notes (or short commings):
* only one type of read supported: type 'byte' (no 'command')
* only one type of write supported: type 'byte_data'
(The two above are more the limitation of the BT869 rather than
the I2C bus.)
* I used the SMBus 'model' rather than the 'bit' model because
I thought it was easier this way.
* failed bus transactions yeild 0xFF, not an error! So, this means
that many drivers instantly latch onto this adapter because all
reads and writes succeed without error. Without the datasheet for
the chip, I can't do much to fix this. (Amazing I got this far!)
BT869/868 notes:
* the BT869 has lots and lots of registers (~50), but can
only read 3 (fairly uninteresting) status registers(!). Right
now all three status registers are read through the 'status' file,
but I haven't decided on the best method for writing to the rest
of the registers.

There are now two new insmod parameters, and the #define has disappeared
force: if set to anything but zero, this enables the PIIX4 as the old
#define did.
force_addr: This first sets a new I/O port address for the PIIX4, and
afterwards enables it. Supercedes 'force'.
Note that using force_addr is very, very dangerous if you do not know
what you are doing. On the other hand, it was very easy to add, and can
be a big help if your BIOS doesn't set correct addresses.

* Removed unnecessary MOD_INC/DEC_USE_COUNT in host adapter drivers
(i2c-via bit-lp bit-velle)
You can now rmmod adapters even when they have registered clients.
Without this, you would have to detach the clients first. Only way of doing
this is to rmmod the client drivers, but the same drivers might be used to
access clients behind other hosts.

It compiles now cleanly against kernel 2.0.36; I checked, double-checked and
cross-checked.

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.

integrated LM78, so the driver is only a customized copy of lm78.c
This southbridge can also do i2c, but this not enough documented in
the datasheet. So i2c is currently not supported.
Some cosmetic changes for VIA driver and documentation.

It tries to delete bit-via.o, bit-mb.o, isa.o and piix4.o in the module
install directory.

lm_sensors2 source tree. Improvements in VIA driver,
now checks revision code and refuses to load the
module if bit_test (in algo-bit) fails.
(Also fixes previous unsuccessfull CVS commit)

I really hope I did not forget an add or remove. If strange things happen
when you compile, please let me know.
There may still be problems with the EXPORT_* stuff; it seems to work now
for kernel 2.0.36pre19, but it may give trouble for earlier kernels. We
need to check that.
Some i2c modules may be a bit verbose at this moment.

I added two new make file 'includes': busses/Module.mk and chips/Module.mk
Frodo- You may want to review the makefile structure to make sure that
the system works as you intended.
Note: The docs still need to be updated to reflect the new file arrangement,
but at least it builds!

Read the intro; it describes how you can use CVS to diff between old releases.
Stupid copyright typo in piix4.c fixed
git-svn-id: http://lm-sensors.org/svn/lm-sensors/trunk@146 7894878c-1315-0410-8ee3-d5d059ff63e0
* Fixed FORCE_PIIX4_ENABLE bus (misspelled function call)
* Added Kyösti's mail about the VIA chipset to the doc directory, as
temporary placeholder

* Somehow, i2c-proc did not yet use the i2c_adapter_id call. This must have
slipped through.
* isa.o and smbus.o changes I made to make them less noisy had a small
error (no return value), which caused strange device detections.
* Added /proc/bus/i2c module-count monitoring - somehow, this slipped
through, too.

access unimplementable functionality. And removed a #if which could never
become true anyway from i2c-proc.c.

* Changed test in lm75 setup code to 'read/write returns < 0' instead of
(old) 'read/write returns 0xff'. Nowadays, we can see the difference
between an error and a 0xff result, after all.
* Introduced constants used by PIIX4 for transaction types. These are
*not* the same as those in smbus.h.
* Some small code optimalizations in piix4.o.
git-svn-id: http://lm-sensors.org/svn/lm-sensors/trunk@40 7894878c-1315-0410-8ee3-d5d059ff63e0
* PIIX4: better names in /proc files
* sensors.c: fixed bug which prevented registration of non-ISA clients
Status:
* lm75 inserts happily and interacts with the PIIX4 correctly
* lm75 readings are still wrong (all 0xff)
* lm75 insertion with ISA bus present causes oops
git-svn-id: http://lm-sensors.org/svn/lm-sensors/trunk@39 7894878c-1315-0410-8ee3-d5d059ff63e0
* /proc/bus/i2c printed garbage if more than one adapter was registered
* There was a double line in piix4.c in the delay function
