Subject: [PATCH 32/74] clockevents/drivers/sun4i: Migrate to new 'set-state' interface Date: Mon, 10 Aug 2015 11:51:49 +0200 Message-Id: <1439200352-26767-32-git-send-email-daniel.lezcano@linaro.org> X-Mailer: git-send-email 1.9.1 In-Reply-To: <1439200352-26767-1-git-send-email-daniel.lezcano@linaro.org> References: <55C87382.4070309@linaro.org> <1439200352-26767-1-git-send-email-daniel.lezcano@linaro.org> Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 2721 Lines: 85 From: Viresh Kumar 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.
