The restart-handler series from Guenter Roeck got accepted recently and implements among other things also the restart handler in the samsung watchdog driver and where applicable in the clock drivers. So there is no need for having the restart callbacks in s3c24xx boards anymore. Signed-off-by: Heiko Stuebner <heiko@sntech.de> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>
