Some LVDS panels, such as the innolux,g101ice-l01 support multiple LVDS
data mapping modes, which can be configured by strapping a dataformat
pin on the display to a specific voltage.
This can be particularly useful for using the jeida-18 format, which
requires only 3 instead of 4 LVDS lanes.
This series moves the data-mapping property for LVDS panels in a
separate file and optionally adds it to simple-panel when matching to
the innolux,g101ice-l01 compatible. This property allows to override
the default data mapping set in the panel description in simple-panel.
The last patch in this series actually adds the driver support for
parsing the data format override device tree property and modifying the
corresponding values for bit per color and media bus format in the panel
descriptor.
Best regards
Johannes
