G156HAN04.0 is a Color Active Matrix Liquid Crystal Display composed of
a TFT LCD panel, a driver circuit, and LED backlight system. The screen
format is intended to support the 16:9 FHD, 1920(H) x 1080(V) screen
and 16.7M colors (RGB 8-bits) with LED backlight driving circuit.
All input signals are LVDS interface compatible.

G156HAN04.0 is designed for a display unit of notebook style
personal computer and industrial machine.

V2: - Rebase the patch
    - Fix up commit message
    - Tx parameter comments are retained, they refer to datasheet
      timings and are generally useful when checking if the timing
      requirements are properly fulfilled
