Since 43cc71eed1250755986da4c0f9898f9a635cb3bf, the platform modalias is
prefixed with "platform:". Add MODULE_ALIAS() to the hotpluggable watchdog
drivers, to re-enable auto loading.[dbrownell@users.sourceforge.net: more drivers; registration fixes]

I noticed this while testing the latest code. I'm not sure if it is required,
but the normal (or LSB) timeout value is set to zero, so the MSB should
be as well to stay consistent.If the chip revision is >= 8, set MSB of the 16-bit timeout value to zero
when disabling the watchdog in it8712f_wdt_disable().Signed-off-by: Andrew Paprocki

This patch corrects an error in the driver it8712f_wdt. You cannot set
the 16-bit WDT_TIMEOUT access as a 16-bit outw, because the byte
ordering will be wrong. So just do the high 8 bits as a separate
access.Signed-off-by: Oliver Schuster

On my HP DL380 G5 system running a 64-bit kernel, loading the hpwdt
driver causes a crash because the driver attempts to ioremap an
invalid physical address. This is because the driver has an incorrect
definition of the SMBIOS table entry point structure: the table
address is only a 32-bit quantity, and making it a u64 means that the
high-order 32 bits end up containing garbage.Correcting the structure definition fixes the driver so that it loads
without any problems on my system.Signed-off-by: Roland Dreier

Hp is providing a Hardware WatchDog Timer driver that will only work with the
specific HW Timer located in the HP ProLiant iLO 2 ASIC. The iLO 2 HW Timer
will generate a Non-maskable Interrupt (NMI) 9 seconds before physically
resetting the server, by removing power, so that the event can be logged to
the HP Integrated Management Log (IML), a Non-Volatile Random Access Memory
(NVRAM). The logging of the event is performed using the HP ProLiant ROM via
an Industry Standard access known as a BIOS Service Directory Entry.Signed-off-by: Thomas Mingarelli

The audit of _p usage shows various drivers assume inb_p is somehow atomic.
Of course it isn't and the delay can be split from the I/O cycle causing a
timing violation on chips that matter (eg this one)With the proposed use of udelay() for some _p delays this will cease to be
a mostly theoretical bug (as the delay stall is unsplittable) and wants
fixing.Lots of other drivers need fixing this way too.

These are derivatives of the AT32AP7000 chip, which means that most of

This patch enables the watchdog to read out the reset cause after a boot and
provide this to the user.The driver will now also return -EIO if probed when booting from a watchdog
reset. This is due to a silicon errata in the AT32AP700x devices.Detailed description and work-arounds can be found in the errata section of the
datasheet avilable from
