I've downloaded AppleUSBOHCI sources, and it looks like it generally checks if there's "AAPL,clock-id" present. If it's not it turns off power management for this OHCI controller and shows it as expansion card instead of built-in. Just like with EHCI controllers. The problem is that, when I add "AAPL,clock-id" into OHCI's DSM method OSX stops detecting this controller (when I add it to one of EHCI controllers everything is fine)
Code:
Device (OHC1)
{
Name (_ADR, 0x00120000)
Name (_PRW, Package (0x02)
{
0x0B,
0x03
})
Method (_S3D, 0, NotSerialized)
{
If (LEqual (OSFL, 0x02))
{
Return (0x02)
}
Else
{
Return (0x03)
}
}
Method(_DSM, 4, NotSerialized)
{
Store (Package (0x0B)
{
"device-id",
Buffer (0x04)
{
0x97, 0x43, 0x00, 0x00
},
"AAPL,clock-id",
Buffer (One)
{
0x01
},
"AAPL,current-available",
0x0FA0,
"AAPL,current-extra",
0x044C,
"AAPL,current-in-sleep",
0x0FA0,
Buffer (One)
{
0x00
}
}, Local0)
DTGP(Arg0, Arg1, Arg2, Arg3, RefOf (Local0))
Return (Local0)
}
}
Any ideas ?
