From 3078c8df2c03ebad334e1efe7e0867d8b0cd2764 Mon Sep 17 00:00:00 2001 From: Viresh Kumar Date: Thu, 16 Jul 2015 16:56:32 +0530 Subject: [PATCH] unicore/time: Migrate to new 'set-state' interface Migrate unicore 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. We weren't doing anything for PERIODIC or RESUME modes and so their callbacks aren't implemented.
