[PATCH v2 02/10] dt-bindings: display: bridge: thc63lvd1024: Document dual-link operation

[Laurent Pinchart]

The THC63LVD1024 LVDS decoder can operate in two modes, single-link or
dual-link. In dual-link mode both input ports are used to carry even-
and odd-numbered pixels separately. Document this in the DT bindings,
along with the related rules governing port and usage.

+The device can operate in single-link mode or dual-link mode. In single-link
+mode, all pixels are received on port at 0, and port at 1 shall not contain any
+endpoint. In dual-link mode, even-numbered pixels are received on port at 0 and
+odd-numbered pixels on port at 1, and both port at 0 and port at 1 shall contain
+endpoints.
