+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.

+      phandle to companion OLDI transmitter. This property is required for both
+      the OLDI TXes if they are expected to work either in dual-lvds mode or in
+      clone mode. This property should point to the other OLDI TX's phandle.

+      Boolean property to mark the OLDI transmitter as the secondary one, when the
+      OLDI hardware is expected to run as a companion HW, in cases of dual-lvds
+      mode or clone mode. The primary OLDI hardware is responsible for all the
+      hardware configuration.
