From 6de6c977bdf61b1ca6f321aba468275c32952d79 Mon Sep 17 00:00:00 2001 From: Viresh Kumar Date: Thu, 18 Jun 2015 16:24:37 +0530 Subject: [PATCH] clockevents/drivers/sun4i: Migrate to new 'set-state' interface Migrate sun4i 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.
