From 6fef79536505be6bf3b0b4ebac70a20f24cffebb Mon Sep 17 00:00:00 2001 From: Lee Jones Date: Thu, 21 Apr 2016 17:07:00 +0200 Subject: [PATCH] ARM: dts: STi: STiH407: Provide generic (safe) DVFS configuration You'll notice that the voltage cell is populated with 0's. Voltage information is very platform specific, even depends on 'cut' and 'substrate' versions. Thus it is left blank for a generic (safe) implementation. If other nodes/properties are provided by the bootloader, the ST CPUFreq driver will over-ride these generic values.
