From d96b7161916f1b5c1a676fba2d54ef0106a88aff Mon Sep 17 00:00:00 2001 From: Chen-Yu Tsai Date: Tue, 6 Jan 2015 10:35:16 +0800 Subject: [PATCH] ARM: dts: sun7i: Add cpu clock reference and operating points to dtsi 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 A20 FEX files in the sunxi-boards repository. Not all boards have the same settings. The settings in this patch are the most generic ones.
