As stated in Documentation/devicetree/bindings/display/panel/panel-mipi-dbi-spi.yml, the MIPI DBI specification defines two power supplies, one for powering the panel and one for the I/O voltage. The panel-mipi-dbi driver currently only supports specifying a single "power-supply" in the device tree.
Add support for a second power supply defined in a new "io-supply" device tree property to make the driver properly configure the voltage regulators on platforms where separate supplies are used.
(Resent from a new email address with proper formatting)
