Add support for acpi probing. SMO3324 is used for st33zp24.
It has been tested with the following acpi node on Minnowboard:
Device (TPM1)
{
Name (_ADR, Zero) // _ADR: Address
Name (_HID, "SMO3324") // _HID: Hardware ID
Name (_CID, "SMO3324") // _CID: Compatible ID
Name (_DDN, "SMO TPM") // _DDN: DOS Device Name
Name (_UID, One) // _UID: Unique ID
Method (_CRS, 0, NotSerialized) // _CRS: Current Resource Settings
{
Name (SBUF, ResourceTemplate ()
{
SpiSerialBus (0, PolarityLow, FourWireMode, 8,
ControllerInitiated, 4000000, ClockPolarityLow,
ClockPhaseFirst, "\\_SB.SPI1",
0x00, ResourceConsumer, ,)
GpioInt (Edge, ActiveHigh, ExclusiveAndWake, PullNone, 0x0000,
"\\_SB.GPO2", 0x00, ResourceConsumer, ,)
{ // Pin list
0x0001
}
GpioIo (Exclusive, PullDefault, 0x0000, 0x0000, IoRestrictionOutputOnly,
"\\_SB.GPO2", 0x00, ResourceConsumer, ,)
{ // Pin list
0x0002,
}
})
Return (SBUF) /* \_SB_.SPI1.TPM1._CRS.SBUF */
}
Method (_STA, 0, NotSerialized) // _STA: Status
{
Return (0x0F)
}
}
