Komeda HW can support dual-link which splits display frame to two halves
(left/link0, right/link1) and output them by two output links.
Due to the halved pixel rate of each link, the pxlclk of dual-link can be
reduced two times compare with single-link.
For enabling dual-link:
- The DT need to configure two output-links for the pipeline node.
- Komeda enable dual-link when both link0 and link1 have been connected.
Example of how the pipeline node will look like for dual-link setup
pipe0: pipeline@0 {
clocks = <&fpgaosc2>;
clock-names = "pxclk";
reg = <0>;
#address-cells = <1>;
#size-cells = <0>;
port@0 {
reg = <0>;
#address-cells = <1>;
#size-cells = <0>;
dp0_pipe0_link0: endpoint@0 {
reg = <0>;
remote-endpoint = <&dlink_connector_in0>;
};
dp0_pipe0_link1: endpoint@1 {
reg = <1>;
remote-endpoint = <&dlink_connector_in1>;
};
};
};
