Or it is because the PNP0C40 device depends on GpioInt from PMIC
which isn't available...

            Method (_CRS, 0, NotSerialized)  // _CRS: Current Resource Settings
            {
                Name (CBUF, ResourceTemplate ()
                {
                    GpioInt (Edge, ActiveBoth, ExclusiveAndWake, PullUp, 0x0BB8,
                        "\\_SB.PCI0.I2C7.PMI2", 0x00, ResourceConsumer, ,
                        )
                        {   // Pin list
                            0x0016
                        }
                })
                Return (CBUF) /* \_SB_.TBAD._CRS.CBUF */
            }

Thanks,
