2009-09-18[WATCHDOG] fix book E watchdog to take WDIOC_SETTIMEOUT arg in secondsChris Friesen
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.

2008-11-08powerpc: Fix Book-E watchdog timer interval settingMatthias Fuchs
This patch fixes the setting of the Book-E watchdog timer interval setup on initialization and by ioctl(). On initialization the period bits have to be masked before setting a new period. In WDIOC_SETTIMEOUT ioctl we have to use the correct mask.

2008-08-06[WATCHDOG] Coding style - Indentation - part 2Wim Van Sebroeck
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.

2008-05-25[WATCHDOG] Fix booke_wdt.c on MPC85xx SMP system'sChen Gong
On Book-E SMP systems each core has its own private watchdog. If only one watchdog is enabled, when the core that doesn't enable the watchdog is hung, system can't reset because no watchdog is running on it. That's bad. It means we must enable watchdogs on both cores. We can use smp_call_function() to send appropriate messages to all the other cores to enable and update the watchdog.
