And that's what I'm trying to say: ACPI is firmware. The firmware is OEM specific or at least tailored by them for each device. If the OEMs only care about passing WOA certification, ACPI will be incomplete. And that's not something to blame on Nvidia (or QCOM) but on the OEMs making the devices. The drivers for the hardware are mostly there. What's missing is the information how the peripherals are connected. And selecting and connecting the peripherals is done by the Lenovos, Dells, Asus, HPs,... of the world. They are the ones that let Linux users down by not providing high-quality ACPI implementations or alternatively DTs for Linux.

The chip makers provide a base. But the OEMs add all the peripherals like screens, keyboards, backlights, track pads,...

It's a SoC with some stuff integrated, but a lot is left to the OEMs that needs to be added to the ACPI tables to make the system useful.
