[PATCH v4 0/3] ALSA: hda/tas2781: Add tas2781 driver for SPI.
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.

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.

A nitpicking: better to align with other lines (i.e. with *-objs instead of *-y).
The main problem here is, though, that this commit will break the build, because you introduced a Kconfig that can be enabled, while the corresponding code for snd-hda-scodec-tas2781-spi isn't present yet. This is bad for the git-bisection.
You'd need to reorganize better how the code is added piece-by-piece.
thanks,

While you see no side effects, the 'objs' is reserved for user space, while 'y' should be used in the kernel code.
See Documentation/kbuild/makefiles.rst "Composite Host Programs", mind the word "host" meaning.

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.

--- v4: - Move include of sound/tas2781-dsp.h to c source file tas2781_hda_spi.c, tas2781_spi_fwlib.c, as it's not needed in header file tas2781-spi.h - Use page and book number define in other micro define - Change 4000000 to (4 * HZ_PER_MHZ) - Add define for calibration variable name and size in UEFI. - Remove structure tasdevice & tasdevice_irqinfo, and move variables in to structure tasdevice_priv - Remove some unused variables in sttructure tasdevice_priv - Remove function declare of tascodec_init(), use tascodec_spi_init() - Remove function declare of tasdevice_remove() - Add array_size.h included in tas2781_hda_spi.c - Add cleanup.h included for change mutex to guard - Add units.h included - Include tas2781-dsp.h - Remove unused variables in tas2781_hda structure - Change 0xff to GENMASK(7, 0) - Change 128 to define of max page size - Change code as all variables was moved to tasdevice_priv structure - Change comments for error in book write, or page write - Remove initial of ret, and return 0 directly - Change comments for wrong typo, add space in front and end - Add check for bulk read, max size should be a page size - Change usleep_rang() to fsleep() - Change mutex_lock to guard(mutex), and remove mutex_unlock() - Change tasdevice_spi_init() to void from int as no value return required - Change second parameter to sizeof - Remove tasdevice_clamp(), use clamp() - Add compatible with old hardware id "TIAS2781" - Remove cs_gpio and spi device in tas2781_read_acpi() as use default CS - Change dev-index check, return -EINVAL if it's <= 0 - Change 0xFF to U8_MAX - Remove GPIO get for chip-select, use default from SPI device - Perform RESET in first AMP only as all AMPs share same RESET pin - return 0 directly in some simple routine to avoid variable initial - Change comments for function which was used by system - Change "ON" "OFF" to function str_on_off(...) - Change format of GUID - Add temp buffer for first efi.get_variable() - Free data if it was allocated - Change format of debug message of calibration date time print - Remove total_sz = 0, as it's not needed - Move save_calibration to after tuning_switch to avoid calibration data overwrite - Remove dev from structure tasdevice_hda, use dev in tasdevice_priv - Remove 0 from { "tas2781-hda", 0}, & {"TXNW2781", 0}, 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;

That's far little description than wished. You can copy the contents of your cover letter to here, for example, for more detailed information.
Second, and most: this patch breaks again the build. You added the code calling functions that aren't defined yet (appearing in the patch 3).
Also, some functions seem defined but not really used, e.g. tasdevice_spi_calbin_remove(), and some are not needed to be global functions.
thanks,
Takashi

When this is no independent module but also included in tas2781-spi driver module, you don't need MODULE_*() for this file. Otherwise they conflict with the definitions in tas2781_hda_spi.c.

v4:
- Add types.h included
- Add tas2781-dsp.h included
- Change error bit define from 0x40000000 to BIT(31)
- Remove pre-block process as no active_dev needed
- Change usleep_range() to fsleep()
- Move variables froblk_offsetm tasdevice to tasdevice_priv
- Move subblk_offset initial into default
- Remove active_dev check
- Move variables into tasdevice_priv structure
- Change format for condition check in if
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.
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().
