The unified device properties API -already supports passing platform data via properties so let's take -advantage of that and allow probe drivers to pass set of properties to the -host controller driver. - -In order to do that we need to be able to modify the MFD cell corresponding -the host controller, so make the core driver to take copy of the cell -instead of using it directly. Then we can assign info->pset to the -resulting copy of a cell and let the MFD core to assign that to the -resulting device. - -Signed-off-by: Mika Westerberg <mika.westerberg@linux.intel.com> -Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> -Signed-off-by: Rafael J.
