2006-06-20[WATCHDOG] convert AT91RM9200 watchdog to platform driverAndrew Victor
Converted to a platform driver. Added suspend/resume support - the watchdog is disabled during the sleep states. Original patch from David Brownell. Signed-off-by: Andrew Victor <andrew@sanpeople.com> Signed-off-by: Wim Van Sebroeck <wim@iguana.be> Signed-off-by: Andrew Morton <akpm@osdl.org>
2006-06-20[WATCHDOG] add WDIOC_GETTIMELEFT ioctlWim Van Sebroeck
Some watchdog drivers have the ability to report the remaining time before the system will reboot. With the WDIOC_GETTIMELEFT ioctl you can now read the time left before the watchdog would reboot your system. The following drivers support this new IOCTL: i8xx_tco.c, pcwd_pci.c and pcwd_usb.c .

2006-05-15[WATCHDOG] i8xx_tco.c - remove support for ICH6 + ICH7Wim Van Sebroeck
Temporary remove support for ICH6 + ICH7. In these newer TCO's the watchdog timer has changed: the TCO_TMR register is not at the TCOBASE+0x1 offset, but changed it's place to TCOBASE+0x12 and became 10 bit long [0:9]. (Kernel BUG 6031). ICH6 + ICH7 support will be added in a new driver. Code is under test. Signed-off-by: Wim Van Sebroeck <wim@iguana.be> Signed-off-by: Andrew Morton <akpm@osdl.org>

2006-01-14[PATCH] Watchdog: Winsystems EPX-C3 SBCCalin A. Culianu
This is a 2.6 patch that adds support for the watchdog timer built into the EPX-C3 single board computer manufactured by Winsystems, Inc. Driver details: This is for x86 only. This watchdog is pretty basic and simple. It is only configurable via jumpers on the SBC, and it only has either a 1.5s or 200s interval. The watchdog can either be auto-configured to start as soon as the machine powers up (bad idea for the 1.5s interval!) or it can be enabled and disabled by writing to io port 0x1ee. Petting the watchdog involves writing any value to io port 0x1ef. The only unfortunate thing about this watchdog (and it is not at all uncommmon in watchdogs that linux supports) is that it is not a PCI or ISA-PNP device and as such it isn't at all probeable. Either the watchdog exists as 2 bytes at 0x1ee, or it doesn't. Thus, using this driver on a machine that doesn't have that watchdog can potentially hang/crash the system, etc. So only use this driver if you in fact are on a Winsystems EPX-C3 SBC. Anyway this driver fits into the already-existing watchdog framework quite nicely and I already tested it on my EPX-C3 and it works like a charm. Signed-off-by: Calin A.

Cleanup for the ARM-only watchdog driver wdt977. This is probably the last update, since we want to merge with w83977f_wdt.

2006-01-09[PATCH] ppc32: m8xx watchdog updateMarcelo Tosatti
This updates m8xx_wdt as follows: 1) Remove now obsolete fpos check in the write() function. The driver is currently non functional due to this bug. 2) Use in/out macros for register access. 3) Allows m8xx_wdt to use a kernel timer instead of the builtin RTC/PIT for keep-alive trigger (which is responsible for servicing the watchdog until an userspace application takes over). For instance Cyclades PRxK boards (MPC 855T based) have a non-functional internal RTC/PIT unit. Behaviour for boards with RTC/PIT is unchaged. 4) The last change required moving the RTCSC register setting code to a weak function which can be overriden by board specific files. Otherwise the timer init code trashes the register making it impossible for m8xx_wdt to detect the situation.
