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
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]>
---
v2:
- Remove file name in tas2781_spi_fwlib.c.
- Remove #include <linux/i2c.h> as it not needed in SPI mode.
- Change TAB to speace in micro define in tas2781_spi_fwlib.c.
- Change to up-case for DSP.
- Change all of multi-line comments format, empty first line.
- Change all of sizeof(struct xx) to sizeof(*xx).
- Remove Explicit casting for variables compare to avoid possible fault.
- Return directly without goto.
- Change 1 << xx to BIT(xx).
- Remove deviceNumber[] as current SPI device will support one device only.
- Add memory free before return error.
- Change "buf[offset]; offset += 1" to buf[offset++].
- Remove some debug information print.
- Change firmware binary to single device mode.
- Change all bexx_to_cpup() to get_unaligned_bexx().
- Remove ndev process as current SPI device support single device only.
- Remove chn and chnend for single device support only.
- Change all of registers read/write function, remove parameter chn.
- Create new function for single write, burst write, delay, field write
in tasdevice_process_block().

2.40.1
Main source code for tas2781 driver for SPI.
Signed-off-by: Baojun Xu <[email protected]>
---
v2:
- Update information in file header of tas2781-spi.h.
- Remove useless micro define.
- Change TASDEVICE_I2CChecksum to TASDEVICE_Checksum
- Remove enum control_bus as current code support SPI only.
- Remove device define as current code support TAS2781 only.
- Remove spi_device **spi_devs in structure tasdevice_priv.
- Remove cal_binaryname in structure tasdevice_priv.
- Remove ndev in structure tasdevice_priv.
- Change isacpi and isspi, replace by control_bus(I2C or SPI).
- Remove void tasdevice_spi_dsp_remove(void *context).
- Add acpi_device and irq in structure tas2781_hda in tas2781_hda_spi.c.
- Remove parameter chn in all of registers access functions.
- Add tascodec_spi_init().
- Add chip select gpio set for SPI device.
- Change tasdevice_tuning_switch() to tasdevice_spi_tuning_switch().
- Change device offset from tas_priv->ndev to tas_priv->index.
- Change tasdevice_dsp_remove() to tasdevice_spi_dsp_remove().
- tasdevice_prmg_load() to tasdevice_spi_prmg_load().
- Change tasdevice_config_info_remove() to
tasdevice_spi_config_info_remove().
- Add one dummy byte shift when read from page 2~127, or not book 0.
- Change tasdevice_spi_change_chn_book() to tasdevice_spi_switch_book()
- Perform put_device(physdev) before error return.
- Change calibration data id to 2781 from 2783 in EFI
- Change calibration data structure name in comments.

Not sure how this is being used.
Also some forward declarations:
+ struct device;
+ struct firmware;
+ struct gpio_desc;
+ struct regmap;
(I might missed something)

For lines likes this, the formatting can be
#define TASDEVICE_RATES \
(SNDRV_PCM_RATE_44100 | SNDRV_PCM_RATE_48000 | SNDRV_PCM_RATE_96000 | \
SNDRV_PCM_RATE_88200)
which from my p.o.v. looks better.

It is unreadable.

.reg = xreg, .rreg = xreg, .shift = xshift, .rshift = xshift, \
.min = xmin, .max = xmax, .invert = xinvert, \

See the difference?
Please, apply this to all twisted macros:
- logical split
- leaving trailing commas
- better formatting

Perhaps you want to define this as it's used a lot in the C and header files.

The indentation here and in some other places is a mess. Please,
take your time to split these in more readable way.

I believe this also can benefit from comments given against previous patches.

Oh, explicit castings should be _rarely_ used. What's the problem with making j

Out of a sudden different style (no {} in 'else' branch). Try to be consistent
