+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>)
+
+Example:
+
+&mux2_i2c2 {
+ status = "okay";
+ clock-frequency = <100000>;
+
+ stdp4028@73 {
+ compatible = "megachips,stdp4028-ge-b850v3-fw";
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ reg = <0x73>;
+
+ interrupt-parent = <&gpio2>;
+ interrupts = <0 IRQ_TYPE_LEVEL_HIGH>;
+
+ ports {
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ port@0 {
+ reg = <0>;
+ stdp4028_in: endpoint {
+ remote-endpoint = <&lvds0_out>;
+ };
+ };
+ port@1 {
+ reg = <1>;
+ stdp4028_out: endpoint {
+ remote-endpoint = <&stdp2690_in>;
+ };
+ };
+ };
+ };
+
+ stdp2690@72 {
+ compatible = "megachips,stdp2690-ge-b850v3-fw";

+Switch to drm_connector_list_iter for any connector_list walking
+----------------------------------------------------------------
+
+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().
