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) { "compatible", "google,cros-ec-uart" } } }) } } BUG=b:147853944 Signed-off-by: Furquan Shaikh <furquan@google.com> Change-Id: I7ccb3633332ce3e388293872af7b22f1867c8465 Reviewed-on: https://review.coreboot.org/c/coreboot/+/42082 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Aaron Durbin <adurbin@chromium.org> Reviewed-by: Paul Menzel <paulepanter@users.sourceforge.net> Reviewed-by: Raul Rangel <rrangel@chromium.org>
