Add the hp-detect gpio for ECS EF20 series laptops based on the _CRS defined in DSDT table.
Method (_CRS, 0, NotSerialized) { Name (SBUF, ResourceTemplate () { I2cSerialBusV2 (0x001A, ControllerInitiated, 0x00061A80, AddressingMode7Bit, "\_SB.PCI0.I2C2", 0x00, ResourceConsumer, , Exclusive, ) GpioInt (Edge, ActiveBoth, SharedAndWake, PullNone, 0x0000, "\_SB.GPO3", 0x00, ResourceConsumer, , ) { // Pin list 0x004F } GpioIo (Shared, PullDefault, 0x0000, 0x0000, IoRestrictionInputOnly, "\_SB.GPO3", 0x00, ResourceConsumer, , ) { // Pin list 0x004F } }) Return (SBUF) /* _SB_.PCI0.I2C2.RTK2._CRS.SBUF */ }
