Subject: [PATCH] omap4: set voltage according to mpu freq
Date: Tue, 28 May 2013 13:51:39 +0200	[thread overview]
Message-ID: <1369741903-24988-1-git-send-email-j.weitzel@phytec.de> (raw)

For OMAP4460 omap4_scale_vcores must set the voltage according to mpu freq.

OPP100  700MHz 1210mV
OPPTB   920MHz 1320mV
OPPNT  1200MHz 1380mV
