Speculatively publishing this, but the entries depend on what the SPI transport reports.
My current version at https://github.com/DankBSD/base always reports USB_PRODUCT_APPLE_WELLSPRING9_ISO actually. The version is extracted from the HID descriptor, like this (Linux applespi developers did not know this is HID, but now we know thanks to OpenBSD and Asahi Linux) and my current transport driver provides it as HID_VERSION.
But really bcm5974 should do it on its own.
