After sucessfully registering the misc device the driver iounmaps the
hardware registers and kfree's the device data structure. Ouch !This was introduced with commit e42311d75 (riowatchdog: Convert to
pure OF driver) and went unnoticed for more than a year :)Return success instead of dropping into the error cleanup code path.

This patch converts the ar7_wdt driver to become
a platform driver. The AR7 SoC specific identification
and base register calculation is performed by the board
code, therefore we no longer need to have access to
ar7_chip_id. We also remove the reboot notifier code to
use the platform shutdown method as Wim suggested.Signed-off-by: Florian Fainelli

The WDIOC_SETTIMEOUT argument is supposed to be a "seconds" value.
However, the book E wdt currently treats it as a "period" which is
interpreted in a board-specific way.This patch allows the user to pass in a "seconds" value and the driver
will set the smallest timeout that is at least as large as specified
by the user. It's been tested on e500 hardware and works as
expected.The patch only modifies the CONFIG_FSL_BOOKE case, the CONFIG_4xx case
is left unmodified as I don't have any hardware to test it on.Signed-off-by: Chris Friesen

This patch contains two fixes:
1)In omap_wdt_probe() the watchdog is reset and disabled. This
requires register access and the clks needs to be enabled temporarily2)In omap_wdt_open() the timer register needs to be reloaded
to trigger a new timer value (the default of 60s)Tested on OMAP34xx platform (Zoom1)

This add watchdog driver for broadcom 47xx device.
It uses the ssb subsytem to access embeded watchdog device.Because the watchdog timeout is very short (about 2s), a soft timer is used
to increase the watchdog period.Note : A patch for exporting the ssb_watchdog_timer_set will
be submitted on next linux-mips merge. Without this patch it can't

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
