2020-11-09acpi: Call acpi_fill_ssdt() only for enabled devicesKarthikeyan Ramasubramanian
Individual drivers check whether the concerned device is enabled before filling in the SSDT. Move the check before calling acpi_fill_ssdt() and remove the check in the individual drivers.

2020-10-21soc/intel/common: Fix/clean up USB4 PCIe virtual/generic driverDuncan Laurie
This driver is for the root port device and needs to reference the parent device for its ACPI scope. Similarly for the debug output it needs to use the parent device, and fall back to the chip name if config->desc is not provided in the devicetree. The UID property is removed. This value is not the same as the port number; according to some docs it should be unique but it is not fully clear what it should be tied to. Regardless, it is not used by the Thunderbolt driver in the kernel. I also renamed some functions/structures to be clear that this is just an ACPI driver for the PCIe root port and not a driver for the root port itself. As part of this I removed the PCI based resource operations and the scan bus function since this device does not have children itself. Finally I added a detailed comment with an example describing what the driver is for and what properties it generates. TEST=boot on volteer and ensure the USB4 root port device and properties are added to the SSDT as described by the comment in chip.h.

2020-10-14soc/intel/common: Add SSDT generation for Intel USB4 PCIe portsDuncan Laurie
This driver will generate the ACPI _DSD for the USB4 PCIe root port properties instead of using static ASL. It assigns the USB4 port number and marks the port as external and hotplug capable.
