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>;

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().
