Display Port on DP1, Display Port on DP0

[djrichter]

Hello,

We have a custom carrier board for Jetson Nano with Display Port on DP1, and Display Port on DP0. Since DP0 is already configured as Display port, I am interested in what changes are required for Display Port on DP1? I have read a prior topic and made changes discussed but could not come to a working system.

I have upload the extracted.dts and a text file (includes dmesg, device Tree changes, and miscellaneous information) to aid in framing the problem.

Thank you,
Darryl

Here are changes made:

hardware/nvidia/platform/t210/porg/kernel-dts/tegra210-porg-p3448-common.dtsi
nvidia,xbar-ctrl = <0 1 2 3 4>; // fixed lanes for our hw
status = “okay”;
hdmi-display { status = “disabled”; };

•                   dp-display { status = "okay"; };
  

hardware/nvidia/platform/t210/common/kernel-dts/t210-common-platforms/tegra210-dp.dtsi
// Copied sor sections and updated nvidia,active-panel to point to sor1 instead of sor0

•           sor1 {
  

•                   nvidia,sor1-output-type = "dp";
  

•                   nvidia,active-panel = <&sor1_dp_display>;
