mb/google/zork: Add support for fingerprint device
This change adds support for fingerprint device in overridetree for
the following variants:
1. berknip
2. morphius
3. trembyle
Generates the following node in SSDT1:
Scope (\_SB.FUR1)
{
Device (CRFP)
{
Name (_HID, "PRP0001") // _HID: Hardware ID
Name (_UID, Zero) // _UID: Unique ID
Name (_DDN, "Fingerprint Reader") // _DDN: DOS Device Name
Method (_STA, 0, NotSerialized) // _STA: Status
{
Return (0x0F)
}
Name (_CRS, ResourceTemplate () // _CRS: Current Resource Settings
{
UartSerialBusV2 (0x002DC6C0, DataBitsEight, StopBitsOne,
0x00, LittleEndian, ParityTypeNone, FlowControlNone,
0x0040, 0x0040, "\\_SB.FUR1",
0x00, ResourceConsumer, , Exclusive,
)
GpioInt (Level, ActiveLow, ExclusiveAndWake, PullDefault, 0x0000,
"\\_SB.GPIO", 0x00, ResourceConsumer, ,
)
{ // Pin list
0x0006
}
})
Name (_S0W, 0x04) // _S0W: S0 Device Wake State
Name (_PRW, Package (0x02) // _PRW: Power Resources for Wake
{
0x0A,
0x03
})
Name (_DSD, Package (0x02) // _DSD: Device-Specific Data
{
ToUUID ("daffd814-6eba-4d8c-8a91-bc9bbf4aa301") /* Device Properties for _DSD */,
Package (0x01)
{
Package (0x02)
{

"google,cros-ec-uart"
}
}
})
}
}
