The panel is Microtips Technology USA MF-101HIEBCAF0[1]. It is a
Dual-Link LVDS panel and supports WUXGA resolution (1920x1200).
Furthermore, it has an i2c based touch controller: Ilitek-ILI2511.
Add DT overlay for the OLDI Panel.

Microtips Technology USA's LVDS Panel MF-101HIEBCAF0[1] uses
ILITEK 2511 capacitative touch sensor to provide touch features on the
display. This panel is used with TI's AM62-SK EVMs.
Enable ILITEK ILI21X touch sensors.
