Hi,
On our custom carrier board, DP0 port is set as HDMI and I try to use this as HDMI. I used tegra186-quill-p3310-1000-c03-00-dsi-hdmi-hdmi.dts and tegra186-quill-p3310-1000-c03-00-dsi-hdmi-dp.dts but there is not a progress. Linux cannot get EDID data from monitor.
dmesg output:

You can also find full dmesg output attached.
I also changed tegra186-quill-p3310-1000-c03-00-dsi-hdmi-hdmi.dts with below parameters but had no effect.
