watchdog: mtx1-wdt: request gpio before using it

drivercore: revert addition of of_match to struct device

2011-05-18T18:32:23+00:00

Commit b826291c, "drivercore/dt: add a match table pointer to struct device" added an of_match pointer to struct device to cache the of_match_table entry discovered at driver match time. This was unsafe because matching is not an atomic operation with probing a driver. If two or more drivers are attempted to be matched to a driver at the same time, then the cached matching entry pointer could get overwritten. This patch reverts the of_match cache pointer and reworks all users to call of_match_device() directly instead. Signed-off-by: Grant Likely

watchdog: mpc8xxx_wdt: fix build

2011-04-07T20:20:24+00:00

Since 1c48a5c93da6313 (dt: Eliminate of_platform_{,un}register_driver) mpc8xxx_wdt no longer builds as it tries to refer to a 'match' variable rather than ofdev->dev.of_match that it checks just before. Signed-off-by: Peter Korsgaard Acked-by: Grant Likely Signed-off-by: Wim Van Sebroeck

watchdog: softdog.c: enhancement to optionally invoke panic instead of reboot on timer expiry

2011-03-29T11:56:22+00:00

This is needed for determining the reason for failure when a softdog timeout occurs. We use softdog to watch for critical application failures and at the minimum a snapshot of the system would help to determine the cause. In such a scenario the application could fail but there isn't a softlockup as such, hence the detect softlockup feature does not help. The patch adds a module parameter soft_panic which when set to 1 causes softdog to invoke panic instead of reboot when the softdog timer expires. By invoking panic we execute kdump if it is configured and the vmcore generated by kdump should provide atleast a minimal idea of the reason for failure.

watchdog: Convert release_resource to release_region/release_mem_region

2011-03-29T11:05:48+00:00

Request_mem_region should be used with release_mem_region, not release_resource. In pnx4008_wdt.c, a missing clk_put is added as well. The semantic match that finds the first problem is as follows: (http://coccinelle.lip6.fr/) // @@ expression x,E; @@ *x = request_mem_region(...) ... when != release_mem_region(x) when != x = E * release_resource(x); // Signed-off-by: Julia Lawall Signed-off-by: Wim Van Sebroeck Cc: stable
