[PATCH 0/4] drm/tiny: panel-mipi-dbi: Support separate I/O voltage supply

[Otto Pflüger]

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.
