This patch converts the iTCO_wdt driver to use the multi-function device
driver model. It uses resources discovered by the lpc_ich driver, so that
it no longer does its own PCI scanning.Signed-off-by: Aaron Sierra

For TCO V1 devices the programmed timeout was twice too long
because the fact that the TCO V1 timer needs to count down
twice before triggering the watchdog, wasn't accounted for.
Also the timeout values in the module description and error
message were clarified. And the _STS registers are 16 bit
instead of 8 bit.Signed-off-by: Pádraig Brady

Bugzilla: 9868 & 10195.
There seems to be a bug into the SMM code that handles TCO Timeout SMI.
Andriy Gapon found that the code on his DG33TL system does the following:
> The handler is quite simple - it tests value in TCO1_CNT against 0x800, i.e.
> checks TCO_TMR_HLT. If the bit is set the handler goes into an infinite loop,
> apparently to allow the second timeout and reboot. Otherwise it simply clears
> TIMEOUT bit in TCO1_STS and that's it.
> So the logic seems to be reversed, because it is hard to see how TIMEOUT can
> get set to 1 and SMI generated when TCO_TMR_HLT is set (other than a
> transitional effect).The only trick we have is to bypass the SMM code by turning of the generation
of the SMI#. The trick can only be enabled by setting the vendorsupport module
parameter to 911. This trick doesn't work well on laptop's.Note: this is a dirty hack. Please handle with care. The only real fix is that
the bug in the SMM bios code get's fixed.Signed-off-by: Wim Van Sebroeck

bugzilla: #12363
commit 7cd5b08be3c489df11b559fef210b81133764ad4 added a second regression:
some Dell's and Compaq's lockup on boot. So we revert most of the code.
The ICH9 reboot issue remains in place and will need some more fixing... :-(Signed-off-by: Wim Van Sebroeck

Bugzilla #9868: On Intel motherboards with the ICH9 based I/O controllers
(Like DP35DP and DG33FB) the iTCO timer counts but it doesn't reboot the
system after the counter expires.This patch fixes this by moving the enabling & disabling of the TCO_EN bit
in the SMI_EN register into the start and stop code.Signed-off-by: Wim Van Sebroeck

* Convert files to UTF-8.
* Also correct some people's names
(one example is Eißfeldt, which was found in a source file.
Given that the author used an ß at all in a source file
indicates that the real name has in fact a 'ß' and not an 'ss',
which is commonly used as a substitute for 'ß' when limited to
7bit.)* Correct town names (Goettingen -> Göttingen)
* Update Eberhard Mönkeberg's address (http://lkml.org/lkml/2007/1/8/313)
