Hi,
Several laptop models employ CSC3551 but lack a corresponding _DSD
block in the ACPI table, including but not limited to:
- Zenbook S 13 OLED (UM5302TA)
- HP Envy x360 ey0xxx
- Lenovo Legion 7i Gen 7
Here are some relevant links:

The following is a snippet of the ACPI table from my laptop (UM5302TA):
---

Name (_SUB, "10431F12") // _SUB: Subsystem ID

0x00, ResourceConsumer, , Exclusive,

I2cSerialBusV2 (0x0041, ControllerInitiated, 0x000F4240,

"\\_SB.GPIO", 0x00, ResourceConsumer, ,

}
GpioIo (Exclusive, PullUp, 0x0000, 0x0000, IoRestrictionInputOnly,

}
GpioIo (Shared, PullUp, 0x0064, 0x0000, IoRestrictionInputOnly,
"\\_SB.GPIO", 0x00, ResourceConsumer, ,
)
{ // Pin list
0x0009
}
GpioInt (Edge, ActiveBoth, Shared, PullUp, 0x0064,
"\\_SB.GPIO", 0x00, ResourceConsumer, ,
)
{ // Pin list
0x0009
}
})
Return (RBUF) /* \_SB_.I2CA.SPKR._CRS.RBUF */
}
Method (_STA, 0, NotSerialized) // _STA: Status
{
If ((AMPD == Zero))
{
Return (Zero)
}
Else
{
Return (0x0F)
}
}
Method (_DIS, 0, NotSerialized) // _DIS: Disable Device
{
}
}

The Cirrus driver for Windows works perfectly. I don't see anything
related to the _DSD stuff in the INF files that came with the driver
(if I read them correctly).
For reference, here are the two INF files from UM5302TA:

I think we should support those devices out of the box, as the Windows
driver does. This problem does not appear to be limited to a single
model; rather, it appears to be a widespread issue. At least, we
should add some quirks for the models listed above.
Thanks.
