+description:
+  The AM625 TI Keystone OpenLDI transmitter (OLDI TX) supports serialized RGB
+  pixel data transmission between host and flat panel display over LVDS (Low
+  Voltage Differential Sampling) interface. The OLDI TX consists of 7-to-1 data
+  serializers, and 4-data and 1-clock LVDS outputs. It supports the LVDS output
+  formats "jeida-18", "jeida-24" and "vesa-18", and can accept 24-bit RGB or
+  padded and un-padded 18-bit RGB bus formats as input.
