* [WATCHDOG] OMAP fixes: enable clock in probe, trigger timer reloadUlrik Bech Hald2009-06-231-0/+7
| | | | | | | | | | | | | | | | | This patch contains two fixes: 1)In omap_wdt_probe() the watchdog is reset and disabled. This requires register access and the clks needs to be enabled temporarily 2)In omap_wdt_open() the timer register needs to be reloaded to trigger a new timer value (the default of 60s) Tested on OMAP34xx platform (Zoom1) Reviewed-by: Kevin Hilman <khilman@ti.deeprootsystems.com> Signed-off-by: Ulrik Bech Hald <ubh@ti.com> Signed-off-by: Wim Van Sebroeck <wim@iguana.be>
* [WATCHDOG] omap_wdt.c: move probe function to .devinit.textUwe Kleine-König2009-04-081-3/+3
| | | | | | | | | | | | | | | | | | | | A pointer to omap_wdt_probe is passed to the core via platform_driver_register and so the function must not disappear when the .init sections are discarded. Otherwise (if also having HOTPLUG=y) unbinding and binding a device to the driver via sysfs will result in an oops as does a device being registered late. An alternative to this patch is using platform_driver_probe instead of platform_driver_register plus removing the pointer to the probe function from the struct platform_driver.

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