From 98a3e804de9158f6e3d568f45c02552af47a0367 Mon Sep 17 00:00:00 2001 From: Alexander Shiyan Date: Sat, 13 Jul 2013 08:34:44 +0400 Subject: ARM: dts: imx27: Add core voltages This patch adds core voltages for i.MX27 CPUs. Only 266 and 400 MHz modes is documented in the datasheet, so we add a 266 MHz frequency for conform this.
