This patch was used to add TAS2781 devices on SPI support in sound/pci/hda.
It use ACPI node descript about parameters of TAS2781 on SPI, it like:
Scope (_SB.PC00.SPI0)
{
Device (GSPK)
{
Name (_HID, "TXNW2781") // _HID: Hardware ID
Method (_CRS, 0, NotSerialized)
{
Name (RBUF, ResourceTemplate ()
{
SpiSerialBusV2 (...)
SpiSerialBusV2 (...)
}
}
}
}
And in platform/x86/serial-multi-instantiate.c, those spi devices will be
added into system as a single SPI device, so TAS2781 SPI driver will
probe twice for every single SPI device. And driver will also parser
mono DSP firmware binary and RCA binary for itself.

2.40.1
Integrate tas2781 configs for HP Laptops. Every tas2781 in the laptop
will work as a single speaker on SPI bus. The code support realtek as
the primary codec.

v3:
- Move HID up to above /* Non-conforming _HID ... */ in scan.c,
for avoid misunderstanding.
- Move HID up to above /* Non-conforming _HID ... */ in

Main source code for tas2781 driver for SPI.
Signed-off-by: Baojun Xu <[email protected]>

v3:
- Change format for some define in tas2781-spi.h.
- Add define for TASDEVICE_MAX_BOOK_NUM, TASDEVICE_MAX_PAGE.
- Move declare of "enum calib_data {" to header file from source file.
- Remove "enum device_catlog_id {" as only one platform was supported now.
- Remove "struct calidata", as we will save pure calibration data only.
- Remove "struct calidata", "enum device_catlog_id" in tasdevice_priv.
- Add calibration_data in tasdevice_priv to save pure calibration data.
- Remove declare of tasdevice_save_calibration() and
tasdevice_apply_calibration(), as it will be used within same c file.
- Add below header files included in tas2781_hda_spi.c:
bits.h, mutex.h, property.h, time.h, types.h.
- Move two micro define to header file tas2781-spi.h.
- Change format of some micro define.
- Change format of some structure.
- Remove irq in tas2781_hda, as have it already in tasdevice_priv.
- Remove some local functions declare as not necessarily.
- Return error if regmap_write() failed.
- Change fixed value 2 to sizeof(data).
- Remove all of EXPORT_SYMBOL_GPL,
as all of function was called within same module.
- Remove empty line after last return in some functions.
- Remove some variable initialyzation.
- Remove variable sub, store acpi_subsystem_id directly.
- Remove wrong comments for device index, it's must, can't be NULL.
- Remove some local variables, use elements in structure directly.
- Append commas in last element of an array.
- Change calibration data process, didn't save all of calibration data in EFI,
get in local, and save pure calibration data in tasdevice_priv.
- Call tasdevice_save_calibration() from function pointer in tasdevice_priv;
- Remove subid as one platform was supported only, needn't check.
- Add initialyzation for local variable.
- Move regmap initialyzation to before acpi read.
- Call tasdevice_apply_calibration() from function pointer in tasdevice_priv;
- Remove MODULE_IMPORT_NS(SND_SOC_TAS2781_FMWLIB), as all functions was
performed within same module.

2.40.1
Firmware download and parser lib for tas2781, it work for spi
device with a single firmware binary file.
Signed-off-by: Baojun Xu <[email protected]>
---
v3:
- Update format and variables declare order.
- Change format of multi conditions for if.
- Remove casting which is not needed.
- Change variables type to avoid casting.
- Remove Unneeded parentheses.
- Change if check to avoid goto.
- Add {} for keep same style.
- Remove some local variables, use elements in structure directly.

Wouldn't below be the same?
return clamp(invert ? max - val : val, 0, max);
(if max can be negative the above won't work, but an original code

Why can't this use reset framework which supports shared / exclusive resets?

EFI_GUID(0x02f9af02, 0x7734, 0x4233,
0xb4, 0x3d, 0x93, 0xfe, 0x5a, 0xa3, 0x5d, 0xb3);

Cleanup loops are better in a while (i--) form.
unsigned int i = ARRAY_SIZE(tas_hda->snd_ctls);
while (i--) {
if (tas_hda->snd_ctls[i])
snd_ctl_remove(codec->card, tas_hda->snd_ctls[i]);
}
BUT, if not yet, just add a support of NULL into snd_ctl_remove(), so it
becomes a NULL-aware one. With that you will have
while (i--)
snd_ctl_remove(codec->card, tas_hda->snd_ctls[i]);
as a traditional pattern for many things in Linux kernel.

I stop here, you need much more cleaning work on these patches. Also, with
cleanup.h and other things in mind you can easily shrink the code by 10%
or so, I will expect -300 LoCs in the next version.

Is that file already in the repository?
If not, I don't see it in this patch either --> dead code.
