Subject: ssb/bcma: add common header for watchdog
X-Git-Tag: accepted/tizen/common/20141203.182822~3243^2~17^2~73
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=bc245cc36c5687dd3fbf6d4a1b3c13d41f9cb189;p=platform%2Fkernel%2Flinux-arm64.git

ssb/bcma: add common header for watchdog

This adds a common header for watchdog functions, so a watchdog driver
just needs to use this and could provide watchdog functionality for ssb
and bcma based SoCs. Patches for a watchdog driver using this interface
will be send later.
