+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.
+
+[JEIDA] "Digital Interface Standards for Monitor", JEIDA-59-1999, February
+1999 (Version 1.0), Japan Electronic Industry Development Association (JEIDA)
+[LDI] "Open LVDS Display Interface", May 1999 (Version 0.95), National
+Semiconductor
+[VESA] "VESA Notebook Panel Standard", October 2007 (Version 1.0), Video
+Electronics Standards Association (VESA)
+
+Those devices have been marketed under the FPD-Link and FlatLink brand names
+among others.
+
+
+Required properties:
+
+- compatible: Must be "lvds-encoder"
+
+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
+
+
+Example
+-------
+
+lvds-encoder {
+	compatible = "lvds-encoder";
+	#address-cells = <1>;
+	#size-cells = <0>;
+
+	ports {
+		#address-cells = <1>;
+		#size-cells = <0>;
+
+		port@0 {
+			reg = <0>;
+
+			lvds_enc_in: endpoint {
+				remote-endpoint = <&display_out_rgb>;
+			};
+		};
+
+		port@1 {
+			reg = <1>;
+
+			lvds_enc_out: endpoint {
+				remote-endpoint = <&lvds_panel_in>;
+			};

+Drivers for the second video output of the GE B850v3:
+   STDP4028-ge-b850v3-fw bridges (LVDS-DP)
+   STDP2690-ge-b850v3-fw bridges (DP-DP++)
+
+The video processing pipeline on the second output on the GE B850v3:
+
+   Host -> LVDS|--(STDP4028)--|DP -> DP|--(STDP2690)--|DP++ -> Video output
+
+Each bridge has a dedicated flash containing firmware for supporting the custom
+design. The result is that, in this design, neither the STDP4028 nor the
+STDP2690 behave as the stock bridges would. The compatible strings include the
+suffix "-ge-b850v3-fw" to make it clear that the driver is for the bridges with
+the firmware specific for the GE B850v3.
+
+The hardware do not provide control over the video processing pipeline, as the
+two bridges behaves as a single one. The only interfaces exposed by the
+hardware are EDID, HPD, and interrupts.
+
+stdp4028-ge-b850v3-fw required properties:
+  - compatible : "megachips,stdp4028-ge-b850v3-fw"
+  - reg : I2C bus address
+  - interrupt-parent : phandle of the interrupt controller that services
+    interrupts to the device
+  - interrupts : one interrupt should be described here, as in
+    <0 IRQ_TYPE_LEVEL_HIGH>
+  - ports : One input port(reg = <0>) and one output port(reg = <1>)
+
+stdp2690-ge-b850v3-fw required properties:
+    compatible : "megachips,stdp2690-ge-b850v3-fw"
+  - reg : I2C bus address
+  - ports : One input port(reg = <0>) and one output port(reg = <1>)

+----------------------------------------------------------------
+
+Connectors can be hotplugged, and we now have a special list of helpers to walk
+the connector_list in a race-free fashion, without incurring deadlocks on
+mutexes and other fun stuff.
+
+Unfortunately most drivers are not converted yet. At least all those supporting
+DP MST hotplug should be converted, since for those drivers the difference
+matters. See drm_for_each_connector_iter() vs. drm_for_each_connector().

+ * This driver creates a drm_bridge and a drm_connector for the LVDS to DP++
+ * display bridge of the GE B850v3. There are two physical bridges on the video
+ * signal pipeline: a STDP4028(LVDS to DP) and a STDP2690(DP to DP++). The
+ * physical bridges are automatically configured by the input video signal, and
+ * the driver has no access to the video processing pipeline. The driver is
+ * only needed to read EDID from the STDP2690 and to handle HPD events from the
+ * STDP4028. The driver communicates with both bridges over i2c. The video
+ * signal pipeline is as follows:
+ *
+ *   Host -> LVDS|--(STDP4028)--|DP -> DP|--(STDP2690)--|DP++ -> Video output
