Commit Message

Xu, Baojun April 30, 2024, 7:25 a.m. UTC 
Integrate tas2781 hda spi driver configs for HP (Varcolac).
Every tas2781 SPI node was added by serial-multi-instantie.c as a SPI device.
The code support Realtek as the primary codec.

Signed-off-by: Baojun Xu <baojun.xu@ti.com>

---
v4:
 - Add old hardware id "TIAS2781" for compatible with old production
 - Add 2 devices in struct smi_node tas2781_hda, to compatible with 4 AMPs
v3:
 - Move HID up to above /* Non-conforming _HID ... */ in scan.c,
   for avoid misunderstanding.
 - Move HID up to above /* Non-conforming _HID ... */ in
   serial-multi-instantiate.c, for avoid misunderstanding.
 - Change objs to y for snd-hda-scodec-tas2781-spi- in Makefile.

Is this for real? I mean you really abused ACPI specifications to get this into
the real products on the market?! If so, never do this again.

_This_ one is non-conforming abuse of ACPI specification and has not to be here
at all. But, if the above is the case, provide the models of the devices and
the excerpt of the DSDT where this broken ID happen, also add a big comment
explaining how comes this happened and that you promise to never happen this
again.

Ditto.

No compile test?
