[PATCH v4 01/13] dt-bindings: display: bridge: Convert lvds-transmitter binding to json-schema

[Fabrizio Castro]

Convert the lvds-transmitter binding to DT schema format using
json-schema.

Signed-off-by: Fabrizio Castro <fabrizio.castro at bp.renesas.com>

---
v3->v4:
* Fixed the description of property "compatible" according to Laurent's
  comments
v2->v3:
* Extracted conversion to dt-schema as per Rob's comment
v1->v2:
* Converted to dt-schema as per Neil's comment

-Parallel to LVDS Encoder
-------------------------
-
-This binding supports the parallel to LVDS encoders that don't require any
-configuration.
-
-LVDS is a physical layer specification defined in ANSI/TIA/EIA-644-A. Multiple
-incompatible data link layers have been used over time to transmit image data
-to LVDS panels. This binding targets devices compatible with the following
-specifications only.

-Required properties:
-
-- compatible: Must be "lvds-encoder"
-
-  Any encoder compatible with this generic binding, but with additional
-  properties not listed here, must list a device specific compatible first
-  followed by this generic compatible.
-
-Required nodes:
-
-This device has two video ports. Their connections are modeled using the OF
-graph bindings specified in Documentation/devicetree/bindings/graph.txt.
-
-- Video port 0 for parallel input
-- Video port 1 for LVDS output
