We want to use one DSI LCD screen to our design.
Are there any document on how to porting customer DSI LCD Driver to TX2?

I get some guideline on the NVIDIA Tegra Linux Driver Package/Display Configuration and Bringup.
After add the following code on the dts file:/hardware/nvidia/platform/t18x/quill/kernel-dts/tegra186-quill-p3310-1000-c03-00-base.dts
host1x {
nvdisplay@15200000 {
status = “okay”;
nvidia,dc-or-node = “/host1x/dsi”;
};
dsi {
status = “okay”;

panel-s-wuxga-8-0 {
status = “okay”;
};
};
};

I get some kernel error message "vpp lcd regulator get failed "by dmesg
Then I just Look into the related driver code, it is related with the function called
regulator_get(dev,“outp”) and regulator_get(dev,“outn”) in the file panel-s-wuxga-8-0.c.
May I ask you what’s the means with outp,outn regulator,and how to fix the issues?

You are on correct way. Those regulators are powered by the pmic on tegra. If you don’t need them, you could just disable it in driver.
