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@intel.com>
   | Closes:
   | https://lore.kernel.org/oe-kbuild-all/202308172137.SthCPFbA-lkp@intel.
   | com/
 - 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@suse.de 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

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

[Shenghao Ding]

Create tas2781 side codec HDA driver for Lenovo Laptops. The quantity
of the speakers has been define in ACPI. All of the tas2781s in the
laptop will be aggregated as one audio speaker. The code supports
realtek codec as the primary codec. Code offers several controls for
digtial/analog gain setting during playback, and other for eq params
setting in case of different audio profiles, such as music, voice,
movie, etc.

Changes in v5:
 - Add comment on dsp/bypass mode in tasdevice_program_put and
   tasdevice_info_programs
 - use pm_runtime_resume_and_get() instead of pm_runtime_get_sync
 - 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")
       }
   }
 - oprimize the indentation
 - fix the ambiguous error message
 - The check of the given value to kcontrol's put func is in the sound/tas2781-comlib.c

 - Seperate snd_kcontrol_new tas2781_dsp_controls into two standalone kcontrol.
 - All the controls set as const static
 - Add static for page_array & rgno_array
 - Remove uncessary blank lines
 - Add descriptions for tas2781_save_calibration
 - remove global addr handling in the code
 - checking subid in switch statement in function tas2781_hda_bind
 - add force firmware load Kcontrol
 - rename the kcontrol name to be more undertandable
 - remove Superfluous cast in tasdevice_fw_ready
 - correct weird line break in function tas2781_acpi_get_i2c_resource
 - correct Referencing adev after acpi_dev_put() in tas2781_hda_read_acpi
 - As to checking the given value in tasdevice_set_profile_id, it seems done
   by the tasdevice_info_profile
 - replace strcpy with strscpy in tas2781_hda_read_acpi
 - rewrite the subid judgement
 - Add tiwai@suse.de into Cc list
 - remove the cast in tas2781_acpi_get_i2c_resource
 - remove else in tas2781_acpi_get_i2c_resource
 - fix the return value in tasdevice_set_profile_id
 - remove unneeded NL in tasdevice_config_get
 - Unifiy the comment style
 - remove ret = 0 in tasdevice_fw_ready
 - remove ret in tas2781_save_calibration
 - remove unused ret in tas2781_hda_playback
 - add force firmware load Kcontrol

Shenghao, your previous patches have been already merged!
Please take the latest sound.git tree before the submission.

Make your changes on top of the latest sound.git tree in a
fine-grained incremental way, and submit those instead *ASAP*, so that
the necessary fixes can be merged for 6.6-rc1.


thanks,

Takashi
