[v4,3/3] drm/panel: add support for Innolux TV123WAM panel

Commit Message

Sandeep Panda April 27, 2018, 9:39 a.m. UTC

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.
