The MIPI DBI specification defines separate vdd (panel power) and vddi (I/O voltage) supplies. Displays that require different voltages for the different supplies do exist, so the supplies cannot be combined into one as they are now. Add a new io_regulator property to the mipi_dbi_dev struct which can be set by the panel driver along with the regulator property.
