* watchdog: booke_wdt: fix ioctl status flagsWim Van Sebroeck2010-05-251-3/+3
| | | | | | | | The WDIOC_GETSTATUS & WDIOC_GETBOOTSTATUS ioctl calls return the WDIOF_* flags and nothing else. Signed-off-by: Wim Van Sebroeck <wim@iguana.be>
* watchdog: booke_wdt: fix build - unconstify watchdog_infoAnton Vorontsov2010-04-271-1/+1
| | | | | | | | | | | | | | | | | commit 42747d712de56cf2087b702d2ad90af114c53138 ("[WATCHDOG] watchdog_info constify") introduced the following build failure: CC booke_wdt.o booke_wdt.c: In function 'booke_wdt_init': booke_wdt.c:220: error: assignment of read-only variable 'ident' Fix this by removing 'const' qualifier from watchdog_info struct.

* [WATCHDOG] fixed book E watchdog period register mask.Luuk Paulussen2010-04-161-1/+1
| | | | | | | | | | A previous fix changed the WDTP function to use the period directly, rather than subtracting from 63. However the mask generation was not changed, so the mask was coming out as 0. This patch fixes it. Signed-off-by: Luuk Paulussen <luuk.paulussen@alliedtelesis.co.nz> Signed-off-by: Wim Van Sebroeck <wim@iguana.be>

* [WATCHDOG] fix book E watchdog to take WDIOC_SETTIMEOUT arg in secondsChris Friesen2009-09-181-4/+53
| | | | | | | | | | | | | | | | | | | | 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.

* powerpc: Fix Book-E watchdog timer interval settingMatthias Fuchs2008-11-081-1/+4
| | | | | | | | | | | | | | 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.

* [WATCHDOG] Coding style - Indentation - part 2Wim Van Sebroeck2008-08-061-9/+9
| | | | | | | | | | | | | | | | | | | | | | | | | 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.

* [WATCHDOG] Fix booke_wdt.c on MPC85xx SMP system'sChen Gong2008-05-251-48/+40
| | | | | | | | | | | | | | | 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.
