Subject: [PATCH] ARM: dts: imx27: Add core voltages
Date: Sat, 13 Jul 2013 08:34:44 +0400 [thread overview]
Message-ID: <1373690084-26760-1-git-send-email-shc_work@mail.ru> (raw)
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.
