Subject: [PATCH v1] ALSA: hda/tas2781: Support ACPI_ID both TXNW2781 and TIAS2781
Support ACPI_ID both TXNW2781 and TIAS2781, TXNW2781 is the only one legal
ACPI ID, TIAS2781 is the widely-used ACPI ID named by our customers, so
far it is not registered. We have discussed this with them, they requested
TIAS2781 must be supported for the laptops already released to market,
their new laptops will switch to TXNW2781.
Signed-off-by: Shenghao Ding <shenghao-ding@...com>
---
Changes in v1:
- Add TXNW2781 into tas2781_acpi_hda_match and move it to the top
- Redefine tas2781_generic_fixup, remove hid param
- TIAS2781 has been used by our customers, see following dstd.dsl. We
have discussed this with them, they requested TIAS2781 must be
supported for the laptops already released to market, their new
laptops will switch to TXNW2781
Name (_HID, "TIAS2781") // _HID: Hardware ID
Name (_UID, Zero) // _UID: Unique ID
Method (_SUB, 0, NotSerialized) // _SUB: Subsystem ID
{
If ((SPID == Zero))
{
Return ("17AA3886")
}
If ((SPID == One))
{
Return ("17AA3884")
}
}
- Add TXNW2781 support in comp_match_tas2781_dev_name
