mfd: Use mfd cell platform_data for tps6105x cells platform bits
Samuel Ortiz [Wed, 11 May 2011 08:33:25 +0000 (10:33 +0200)]
With the addition of a platform device mfd_cell pointer, MFD drivers
can go back to passing platform data back to their sub drivers.
This allows for an mfd_cell->mfd_data removal and thus keep the
sub drivers MFD agnostic. This is mostly needed for non MFD aware
sub drivers.
