Subject: [PATCH 2/5] clocksource: rockchip: remove unnecessary clear irq before request_irq
Date: Wed, 25 May 2016 17:49:59 +0800	[thread overview]
Message-ID: <1464169802-6033-3-git-send-email-wxt@rock-chips.com> (raw)
In-Reply-To: <1464169802-6033-1-git-send-email-wxt@rock-chips.com>

From: Huang Tao <huangtao@rock-chips.com>

rk_timer_interrupt_clear and rk_timer_disable is unnecessary before
request_irq. Timer should keep disabled before booting Linux.
