[PATCH v5 1/2] ALSA: hda/tas2781: Add tas2781 HDA driver

From: Shenghao Ding
Date: Sun Aug 27 2023 - 22:29:18 EST


Integrate tas2781 configs for Lenovo Laptops. All of the tas2781s in the
laptop will be aggregated as one audio device. The code support realtek
as the primary codec.

Changes in v5:
- 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 laptop can 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")
}
}
- rename calib_data properly
- use clamp instead of tas2781_hda_clamp
- Add TXNW2781 support in comp_match_tas2781_dev_name
- | Reported-by: kernel test robot <lkp@xxxxxxxxx>
| Closes:

- remove workaround code for 0x17aa38be, laptop vendor will fix it in acpi.
- rename comp_match_tas2781_dev_name to avoid indentation
- simplify the check of vendor id with Lenovo
- ThinkPad is one of Lenovo's brands, I was suggested me to use
ALC269_FIXUP_THINKPAD_ACPI.
- Add comments on ACARD_SINGLE_RANGE_EXT_TLV
- Add the range check for tas_priv->tasdevice[] in tas2781_acpi_get_i2c_res.
- remove acpi_subsystem_id
- Issue in Laptop 0x17aa38be ACPI talbe caused codec->bus->pci->subsystem_device
is not equal to (codec->core.subsystem_id & 0xffff) in snd_hda_pick_fixup.
The former is 0x3802 and the latter is 0x38be leads to getting the wrong
fixup_id and enter into the wrong entry. Although, this issue has been raised
to the laptop manufacturer, but the ACPI table is locked, cannot be changed
any more. Correct the wrong entry in the code.
- Undo Rename "struct cs35l41_dev_name" to "struct scodec_dev_name" for all, this
data structure seemed useless any more for tas2781
- Ignore the checkpatch complaints in alc269_fixup_tbl
- Drop the hunk which is irrelevant with my code in
alc_fixup_headset_mode_alc255_no_hp_mic
- Add tiwai@xxxxxxx into Cc list
- remove useless index
- combine ALC287_FIXUP_TAS2781_I2C_2 and ALC287_FIXUP_TAS2781_I2C_4 together as
ALC287_FIXUP_TAS2781_I2C, The code view all the tas2781s in the laptop as one instance.
- delete the white space at the end of the line in alc_fixup_headset_mode_alc255_no_hp_mic
