Hi,
The powerdomain framework currently expects to always have a voltagedomain
associated with a given powerdomain. We already have AM33xx which
has no Voltage Controller/Voltage Processor as part of PRCM.
There are more SoCs' to follow starting with AM437x and DRA7xx
which do not have VC/VP. All these SoCs', hence do not support any
form of auto-scaling of voltages, that was possible on earlier OMAPs'
using the VFSM to trigger an i2c communication to the PMIC automatically
on hitting a low power state.
Instead of adding dummy voltage domain data files, like was done for the
AM33xx case, make the powerdomain framework aware of the fact that some
SoCs' might not really have support for auto-scaling of voltages in hw.
Patches are based of 3.10-rc6 and are boot tested on am335x bone.

associated to a pwrdm
