Phoronix: AMD Patches To Generate DeviceTree Nodes For PCI Devices Merged In Linux 6.6

The DeviceTree changes for Linux 6.6 add the ability to generate DeviceTree (DT) nodes for PCI devices. AMD spearheaded this effort for applying DeviceTree overlays to PCI devices containing non-discoverable downstream devices...

For AMD's purposes they appear to be interested in making use of this for their Xilinx Alveo FPBA-based accelerator cards.

Is the FPBA a new thing that I want to learn about, or it’s a typo for:

This support allows for describing hardware peripherals that are present in a PCI endpoint but not auto-discoverable

I know my RX580 has at least one non-auto-discoverable PMBUS endpoint for its VRM controller. There's also one on the motherboard for the CPU, however the generic hwmon driver doesn't use the right scaling factors when reporting voltage and temperature.
