Subject: [PATCH 13/17] ARM: dts: sun4i: Add cpu clock reference and operating points to dtsi
Date: Tue,  6 Jan 2015 10:35:23 +0800	[thread overview]
Message-ID: <1420511727-8242-14-git-send-email-wens@csie.org> (raw)
In-Reply-To: <1420511727-8242-1-git-send-email-wens@csie.org>

The cpu core is clocked from the "cpu" clock. Add a reference to it
in the first cpu node. Also add "cpu0" label to the node.

The operating points were taken from the A10 FEX files in the
sunxi-boards repository. All FEX files have the same settings.
