SSDT-GPI0 confusion - please help

I'm following Dortania's Install Guide for a Broadwell Gen Laptop

https://dortania.github.io/Getting-Started-With-ACPI/Laptops/trackpad-methods/manual.html#checking-gpi0

After check VoodooGPIO isn't attached, I understand need to modify some values to enable the GPI0

Here in the DSDT:

Device (GPI0)

{

Method (_HID, 0, NotSerialized) // _HID: Hardware ID

{

If (LEqual (PCHG, 0x02))

{

Return ("INT3437")

}

​

Return ("INT33C7")

}

​

Name (RBUF, ResourceTemplate ()

{

DWordIO (ResourceProducer, MinFixed, MaxFixed, PosDecode, EntireRange,

0x00000000, // Granularity

0x00000000, // Range Minimum

0x000003FF, // Range Maximum

0x00000000, // Translation Offset

0x00000400, // Length

,, _Y1C, TypeStatic, DenseTranslation)

})

CreateDWordField (RBUF, \_SB.PCI0.GPI0._Y1C._MIN, BMIN) // _MIN: Minimum Base Address

CreateDWordField (RBUF, \_SB.PCI0.GPI0._Y1C._MAX, BMAX) // _MAX: Maximum Base Address

Method (_CRS, 0, Serialized) // _CRS: Current Resource Settings

{

Store (GPMN, BMIN)

Store (GPMX, BMAX)

Return (RBUF)

}

​

Method (_HRV, 0, NotSerialized) // _HRV: Hardware Revision

{

Return (^^LPCB.CRID)

}

​

Method (_STA, 0, NotSerialized) // _STA: Status

{

If (LEqual (GPMN, Zero))

{

Return (Zero)

}

​

If (LAnd (LEqual (OSYS, 0x07DC), LEqual (SMD0, One)))

{

Return (Zero)

}

​

If (LLess (OSYS, 0x07DC))

{

Return (Zero)

}

​

If (LEqual (SMGP, Zero))

{

Return (Zero)

}

​

Return (0x0F)

}

}

But I don't know how to edit to enabling the GPI0 device? it not simple like example in Guide above?
