2011-07-26watchdog: remove empty pm-functionsWolfram Sang1-5/+0
While checking what watchdog drivers usually do in suspend/resume to spot common behaviour for the watchdog framework, I found these drivers which do nothing but add some cruft. Remove it, it is superfluous. New approaches should probably be done with pm_ops anyway. Signed-off-by: Wolfram Sang <w.sang@pengutronix.de> Signed-off-by: Wim Van Sebroeck <wim@iguana.be>

2010-10-28watchdog: iTCO_wdt.c: remove extra pci_dev_put()'s from init codePrarit Bhargava1-2/+0
The iTCO_wdt driver erroneously releases the pci_dev, and causes PCI hotremove to fail because of an incorrect usage count. The probe for this driver does a for_each_pci_dev() which gets a reference for a pci_dev when iTCO_wdt_init() is successful. The for_each_pci_dev() loop puts a reference for a pci_dev when iTCO_wdt_init() fails, so the iTCO_wdt_init() does not need to do any pci_dev_put()'s. The only pci_dev_put() that is required is in the iTCO_wdt_cleanup() function. Signed-off-by: Prarit Bhargava <prarit@redhat.com> Signed-off-by: Wim Van Sebroeck <wim@iguana.be>
2010-10-28watchdog: iTCO_wdt: Cleanup warning messagesPrarit Bhargava1-9/+12
The current iTCO_wdt driver warnings are confusing. Currently when the device driver returns an error the console contains: iTCO_vendor_support: vendor-support=0 iTCO_wdt: Intel TCO WatchDog Timer Driver v1.05 iTCO_wdt: failed to reset NO_REBOOT flag, reboot disabled by hardware iTCO_wdt: No card detected After the patch, iTCO_vendor_support: vendor-support=0 iTCO_wdt: Intel TCO WatchDog Timer Driver v1.05 iTCO_wdt: failed to reset NO_REBOOT flag, device disabled by hardware/BIOS Clean this up and use the word "device" to describe the device.

2010-05-25iTCO_wdt: fix TCO V1 timeout values and limitsPádraig Brady1-9/+20
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.

2010-03-06[WATCHDOG] iTCO_wdt: clean up probe(), modify err msgNaga Chumbalkar1-10/+9
It's possible that the platform is not allowing reboot via TCO timer expiration. Also, differentiate between not finding a chipset that has TCO, and the case where TCO is present but the driver fails to initialize for some reason.

2008-12-03iTCO_wdt: fix typo when setting TCO_EN bitLinus Torvalds1-1/+1
The code used '&= 0x00002000' when it tried to set the TCO_EN bit, which obviously didn't set that bit at all, but instead just reset all the other bits in the SMI_EN register. This bug seemingly caused various random behavior, with Frans Pop reporting that X.org just silently hung at startup and Rafael Wysocki reports the fan spinning with full speed. See http://lkml.org/lkml/2008/12/3/178 http://bugzilla.kernel.org/show_bug.cgi?id=12162 The problem seems to have been triggered by "[WATCHDOG] iTCO_wdt : problem with rebooting on new ICH9 based motherboards" (commit 7cd5b08be3c489df11b559fef210b81133764ad4), but the bogus code existed before that too (in the "supermicro_old_pre_stop()" function), it just apparently never showed up due to different logic. In that commit the broken code got moved around and now gets executed much more. Reported-by: Rafael J.

The iTCO_wdt code was not clearing the correct bits. It now clears the timeout status bit and then the SECOND_TO_STS bit and then the BOOT_STS bit. Note: we should first clear the SECOND_TO_STS bit before clearing the BOOT_STS bit. Signed-off-by: Wim Van Sebroeck <wim@iguana.be>

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.

2008-08-06[WATCHDOG] Coding style - Indentation - part 2Wim Van Sebroeck1-4/+4
This brings the watchdog drivers into line with coding style. This patch takes cares of the indentation as described in chapter 1. Main changes: * Re-structure the ioctl switch call for all drivers as follows: switch (cmd) { case WDIOC_GETSUPPORT: case WDIOC_GETSTATUS: case WDIOC_GETBOOTSTATUS: case WDIOC_GETTEMP: case WDIOC_SETOPTIONS: case WDIOC_KEEPALIVE: case WDIOC_SETTIMEOUT: case WDIOC_GETTIMEOUT: case WDIOC_GETTIMELEFT: default: } This to make the migration from the drivers to the uniform watchdog device driver easier in the future.
