drivers/usb/pci_xhci: Add a driver to generate xHCI ACPI nodes
We can use xhci_for_each_ext_cap to inspect the xHC so we generate the
correct number of device nodes.
Scope (\_SB.PCI0.PBRA)
{
Device (XHC1)
{
Name (_ADR, 0x0000000000000004) // _ADR: Address
Method (_STA, 0, NotSerialized) // _STA: Status
{
Return (0x0F)
}
Name (_PRW, Package (0x02) // _PRW: Power Resources for Wake
{
0x1F,
0x03
})
Device (RHUB)
{
Name (_ADR, Zero) // _ADR: Address
Device (HS01)
{
Name (_ADR, 0x01) // _ADR: Address
}
Device (HS02)
{
Name (_ADR, 0x02) // _ADR: Address
}
Device (SS01)
{
Name (_ADR, 0x03) // _ADR: Address
}
}
Name (_S0W, Zero) // _S0W: S0 Device Wake State
Name (_S3W, 0x04) // _S3W: S3 Device Wake State
Name (_S4W, 0x04) // _S4W: S4 Device Wake State
}
}
BUG=b:154756391
TEST=Boot trembyle and look at ACPI table. See all xHCI nodes.
