* watchdog: fix platform driver hotplug/coldplugKay Sievers2008-04-1112-0/+20
| | | | | | | | | | | | | | Since 43cc71eed1250755986da4c0f9898f9a635cb3bf, the platform modalias is prefixed with "platform:". Add MODULE_ALIAS() to the hotpluggable watchdog drivers, to re-enable auto loading.

* [WATCHDOG] it8712f_wdt Zero MSB timeout byte when disabling watchdogAndrew Paprocki2008-04-061-0/+2
| | | | | | | | | | | | | | 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().

* [WATCHDOG] Fix it8712f_wdt.c wrong byte order accessing WDT_TIMEOUTOliver Schuster2008-04-011-12/+2
| | | | | | | | | | 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 <olivers137@aol.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

* [WATCHDOG] Fix declaration of struct smbios_entry_point in hpwdtRoland Dreier2008-03-061-1/+1
| | | | | | | | | | | | | | | | | | 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.

* [WATCHDOG] it8712f_wdt support for 16-bit timeout values, WDIOC_GETSTATUSAndrew Paprocki2008-03-061-14/+64
| | | | | | | | | | | | This patch adds support for 16-bit watchdog timeout values which are available in chip revisions >= 0x08. Values <= 65535 are seconds precision, otherwise minutes precision is used up to a maximum value of 3932100. Added implementation for WDIOC_GETSTATUS which checks the WDT status bit in the WDT control register.

* [WATCHDOG] HP ProLiant WatchDog driverThomas Mingarelli2008-02-183-0/+939
| | | | | | | | | | | | | | 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.

* [WATCHDOG] wdt: fix lockingAlan Cox2008-01-251-3/+27
| | | | | | | | | | | | | | | | | 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. Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Wim Van Sebroeck <wim@iguana.be> Signed-off-by: Andrew Morton <akpm@linux-foundation.org>
