[PATCH v9 4/4] dt-bindings: drm/panel: Document Innolux TV123WAM panel bindings

[Sandeep Panda]

Innolux TV123WAM is a 12.3" eDP display panel with
2160x1440 resolution, which can be supported by simple
panel driver.

Changes in v1:
 - Make use of simple panel driver instead of creating
   a new driver for this panel (Sean Paul).
 - Combine dt-binding and driver changes into one patch
   as done by other existing panel support changes.

Changes in v2:
 - Separate driver change from dt-binding documentation (Rob Herring).
 - Add the properties from simple-panel binding that are applicable to
   this panel (Rob Herring).
