Can TK1 support NVSR eDP LCD? EXP ,the 11.6' chaimei innolux N116HSE

I enable the NVSR option in kernel and set panel type to edp_i_1080p_11_6, but the kernel cannot boot.What is the matter?

Hi zjj2k,

Could you paste the last dmesg you got?

We don’t support NVSR feature on Tegra.

But it is work fine on TX1. Another 14" AUO LCD is work fine on TK1.

Here is the boot message on TK1 when use the the 11.6’ chaimei innolux N116HSE

If you don’t open NVSR, does the LCD work?

The 11.6’ LCD don’t work，if don’t open NVSR.The 14" AUO LCD is work whether open NVSR or not.

I have confirmed with internal team that we don’t support NVSR on any Tegra OS.

However, if it is bring-up issue, please check with the device tree first.

We have one for your panel “./arch/arm/boot/dts/panel-i-edp-1080p-11-6.dtsi”

and the driver is in “./arch/arm/mach-tegra/panel-i-edp-1080p-11-6.c”

Thanks!
Yes, I have noticed

1, But I have not found the panel-i-edp-1080p-11-6.dtsi
2, In arch/arm/mach-tegra/board-ardbeg-panel.c have follow code

case 1200:
			panel = &edp_i_1080p_11_6;
			ardbeg_disp1_out.type = TEGRA_DC_OUT_NVSR_DP;
			break;
		default:
			panel = &edp_a_1080p_14_0;
			ardbeg_disp1_out.type = TEGRA_DC_OUT_DP;
			break;
		}

I think the out.type TEGRA_DC_OUT_NVSR_DP is for this panel, if have tested this panel on Jetson TK1?

Looks like this device tree is not included in TK1 kernel source but in TX1 source. I will investigate it.

Hi zjj2k,

It is not tested on TK1.

What Ardbeg has is not necessarily compatible with TK1.
