Hi Rob,
Adding Hans. Hans has become something of a Cherry Trail expert.

Your kernel is indeed a bit old, and it is missing a lot of code that
adds USB Type-C and PD support. It also does not have for example a
driver for the internal Intel USB role mux. That driver may not always
be needed (the firmware may be configuring the mux), but I don't know
what is the situation on your platform.
Can you find out the following things for us:
- Does the BIOS program the internal USB role mux, or is the
operating system expected to take care of it?
- How do you interact with the PD controller from the operating
system? Is the PD controller connected to the embedded controller or
to the SoC (or both) via some serial bus like I2C?
- Which PD controller is it? What's the manufacturer and the model?
My guess is that the role mux is again the culprit (it so often is).
If you can test a newer kernel, preferable v4.18, you should be able
to test manually via sysfs if configuring the mux helps. The kernel
option for the mux driver is CONFIG_USB_ROLES_INTEL_XHCI. You can set
it to device role like this:
% echo device > /sys/class/usb_role/intel_xhci_usb_sw-role-switch/role
In case you are not familiar with that mux, it is part of the Intel
xHCI block, and there are two registers in xHCI MMIO that are used for
configuring it. Check ch. 7.4.182:

To me this really sounds like the role mux is not being configured,
but...

Felipe maintains the dwc3 driver. It would be better if he takes a
look at the dwc3 trace output to see if there is anything interesting.
I don't know how to interpret that.

It would be more useful at this stage if you could share the ACPI
tables. If you can send acpidump output, that would be great:
% acpidump -o <file>
