--- Comment #4 from Vandana Kannan <vandana.kannan at intel.com> ---
To enable BLC, VBT version >= 191 needs to have control pin set to 2 (DDI PWM).
This is because only PWM via DDI has been enabled as of now.
This check has to be changed when support for any of the other control pins
would be added.
