If I didn't mess things up here, this should be what the Galileo Gen2
reports:
Device (ADC2)
{
Name (_HID, "INT3495") // _HID: Hardware ID
Name (_CID, "INT3495") // _CID: Compatible ID
Name (RBUF, ResourceTemplate ()
{
SpiSerialBus (0x0000, PolarityLow, FourWireMode, 0x10,
ControllerInitiated, 0x00FE5178, ClockPolarityHigh,
ClockPhaseSecond, "\\_SB.PCI0.SPI0",
0x00, ResourceConsumer, ,
)
GpioIo (Shared, PullDefault, 0x0000, 0x0000, IoRestrictionNone,
"\\_SB.PCI0.GIP0.GPO_", 0x00, ResourceConsumer, ,
)
{ // Pin list
0x0008
}
})
Method (_CRS, 0, NotSerialized) // _CRS: Current Resource Settings
{
Return (RBUF)
}
Method (_STA, 0, NotSerialized) // _STA: Status
{
If (LNotEqual (PTYP, 0x08))
{
Return (Zero)
}
Return (0x0F)
}
}

Yes, for the existing devices: The Galieo is shipped for years with this
DSDT, the IOT2000 for about half a year.
