[PATCH 1/8] ARM: STi: STiH407: Provide generic (safe) DVFS configuration
From: Lee Jones
Date: Mon Jun 22 2015 - 11:46:17 EST
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.
