--- 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. --- sound/pci/hda/tas2781-spi.h | 165 ++++ sound/pci/hda/tas2781_hda_spi.c | 1305 +++++++++++++++++++++++++++++++ 2 files changed, 1470 insertions(+) create mode 100644 sound/pci/hda/tas2781-spi.h create mode 100644 sound/pci/hda/tas2781_hda_spi.c

--- 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. --- sound/pci/hda/tas2781_spi_fwlib.c | 2272 +++++++++++++++++++++++++++++ 1 file changed, 2272 insertions(+) create mode 100644 sound/pci/hda/tas2781_spi_fwlib.c
