Subject: [PATCH 09/18] ARM/lpc32xx/timer: Migrate to new 'set-state' interface
Date: Mon, 6 Jul 2015 16:24:16 +0530 [thread overview]
Message-ID: <79792dd6257c2dbdde4f90a4abbdc742490843b7.1436178990.git.viresh.kumar@linaro.org> (raw)
In-Reply-To: <cover.1436178990.git.viresh.kumar@linaro.org>
Migrate lpc32xx driver to the new 'set-state' interface provided by
clockevents core, the earlier 'set-mode' interface is marked obsolete
now.
This also enables us to implement callbacks for new states of clockevent
devices, for example: ONESHOT_STOPPED.
