Subject: [PATCH 06/23] ARM: at91/dt: at91sam9260: use slow clock where necessary
Date: Fri, 31 Jul 2015 11:39:42 +0200	[thread overview]
Message-ID: <1438335599-3301-7-git-send-email-alexandre.belloni@free-electrons.com> (raw)
In-Reply-To: <1438335599-3301-1-git-send-email-alexandre.belloni@free-electrons.com>

The watchdog, the reset controller, the real-time timer, the shutdown
controller, the timer counters need the slow clock, add it where necessary.
