   4 Subject: [PATCH 111/149] OMAP2+: voltage: enable VC bypass scale method when VC is initialized
   5
   6 VC is initialized first, set default scaling method to VC bypass.
   7 If/when VP is initialized, default scaling method will be changed to
   8 VP force-update.
   9
  10 Enabling VC bypass as default as soon as VC is initialized allows for
  11 VC bypass scaling to work when no VP is configured/initialized for a
  12 given voltage domain.
