Nope, it is "Hardware Reduced (V5) : 0". Now the FADT is also at

I added CONFIG_INPUT_SOC_BUTTON_ARRAY=y, but no joy.
Maybe because the _HID is INTCFD9, only _CID is PNP0C40?
It also has a _DSM with UUID dfbcf3c5-e7a5-44e6-9c1f-29c76f6e059c.
BTW, lsinput already lists two "Power Button" devices,
phys : "PNP0C0C/button/input0"
phys : "LNXPWRBN/button/input0"
None of them generates events in input-events.
