eDP Link Training fails

Hi Wayne,
thank for you quick reply!

Yes I remember that you mentioned DT changes for eDP but I understood those to be only regarding the backlight control pins.

Sorry if my wording about the display setup was confusing. I only ever have a single display or lcd panel connected and am only using DP0 right now. The only difference is the connector I use and of course a standard desktop monitor vs an eDP panel. I attached a picture of how it looks like with a DP connector attached, hopefully that clears things up regarding the hardware setup.

I copied over the prod settings from that file but after flashing I still get this message in the bootlog that prod_c_hbr is missing.

This is how my sor looks like right now:

sor {
			status = "okay";
			nvidia,xbar-ctrl = <2 1 0 3 4>;
			dp-display {
				status = "okay";
			};
			prod-settings {
				prod_c_hbr {
					prod = <
						0x00000590 0x00f00000 0x00400000   //SOR_NV_PDISP_SOR_PLL1_0	23:20=LOADADJ	0x04 
						>;
				};
				prod_c_hbr2 {
					prod = <
						0x00000590 0x00f00000 0x00600000   //SOR_NV_PDISP_SOR_PLL1_0	23:20=LOADADJ	0x06 
						>;
				};
				prod_c_rbr {
					prod = <
						0x00000590 0x00f00000 0x00300000   //SOR_NV_PDISP_SOR_PLL1_0	23:20=LOADADJ	0x03
						>;
				};

			};
		};

This is the other possible setup for the carrier with a DP connection. The other option is an adapter to eDP as seen in the picture of the first post.
