Currently, our customer board has two usb2.0 and pcie#0 x4.But I do not know how to edit dts file to fit this hardware setting. This page “Jetson/TX2 USB - eLinux.org” shows usb dts setting example.But I am so confuse about tx2 dts file.
could you please provide a user manual to explain each dts file and every property in these file under “hardware/nvidia/” folder.
I edit tegra186-quill-p3310-1000-c03-00-base.dts file and tegra186-quill-p3310-1000-a00-00-base.dts file,change pcie property and usb property. But system log show some error message.
max_iso_bw is relaxed to 1875000KB from 0KB
