In one of setup post of pcie config #1 was a good pointer:
But current DTS code has ‘DT_VERSION_2’ thrown into play, what to do?
#if TEGRA_XUSB_PADCONTROL_VERSION >= DT_VERSION_2
xhci@3530000 {
phys = <&{/xusb_padctl@3520000/pads/usb2/lanes/usb2-0}>,
<&{/xusb_padctl@3520000/pads/usb2/lanes/usb2-1}>,
<&{/xusb_padctl@3520000/pads/usb3/lanes/usb3-0}>;
phy-names = "usb2-0", "usb2-1", "usb3-0";
status = "okay";
};
else
xhci@3530000 {
status = “okay”;
phys = <&tegra_xusb_padctl TEGRA_PADCTL_PHY_UTMI_P(0)>,
<&tegra_xusb_padctl TEGRA_PADCTL_PHY_UTMI_P(1)>,
<&tegra_xusb_padctl TEGRA_PADCTL_PHY_USB3_P(0)>;
phy-names = “utmi-0”, “utmi-1”, “usb3-0”;
nvidia,boost_cpu_freq = <800>;
};
