Cover letter [PATCH v2 0/2] Remove unused voltagedomain data for AM33xx
Quoted 15 lines · Rajendra Nayak
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.

Thanks, queuing up this series with ack from Santosh and tested-by from Afzal. I'll try, but not sure if it can make it for v3.11.
