Subject: [PATCH v7 1/1] ALSA: hda/tas2781: Add tas2781 hda driver based on SPI
Integrate tas2781 hda spi driver configs for HP (Varcolac).
Every tas2781 SPI node was added by serial-multi-instantie.c as a single
SPI device. The code support Realtek as the primary codec.
Signed-off-by: Baojun Xu <baojun.xu@ti.com>
---
v7:
- Add new project Gemtree (0x103c8daa) support for tas2781 spi driver.
v6:
- Remove client in tasdevice_priv struct as it was not used.
- Change format for tasdevice_spi_dev_write() in tas2781_hda_spi.c.
- Change update bits function to read & write mode, as tas2781 use last bit
to mask read & write, it cause regmap_update_bits work not as our expected.
- Add element in tas2781_snd_controls, tas2781_prof_ctrl,
tas2781_dsp_conf_ctrl, to support second device.
Previous version add sound card for first index only.
- Change calibration registers address declaire to TASDEVICE_REG() mode.
- Add snd_ctl_new1() for second device.
- Change format for tas2781_hda_unbind() to fit 79 chars in one line.
- Remove client for spi as it was not used.
- Remove unused variables.
- Remove cur_prog clean in runtime_suspend().
- Remove unused variables.
- Add tasdevice_spi_tuning_switch() in runtime_resume.
- Remove cur_prog clean in system_resume().
- Add tuning switch if playback started in system_resume().
- Change TASDEVICE_PAGE_REG to TASDEVICE_REG_ID in tas2781_spi_fwlib.c.
- Remove calibration binary load functions as data will be loaded from EFI.
v5:
- Combined all modification into one patch for pass the compile.
- Remove old hardware id "TIAS2781" as no production on market.
- Change max page size to 256 in tas2781-spi.h.
- Change book reg from 127 to GENMASK(7, 1), as one bit shift is needed.
- Change register address define as one bit shift needed for offset.
- Change block check sum comments to Firmware block from I2C.
- Change define of (page + reg) to TASDEVICE_PAGE_REG from TASDEVICE_PGRG.
- Change to lower case in defined value.
- Add registers default value table in tas2781_hda_spi.c
- Change rang_max to 256 * 256.
- Add zero_flag_mask in regmap_config.
- Change max_register to 256 * 256.
- Add registers default table into structure regmap_config.
- Change parameter from book number to whole register address.
- Remove page 0 switch as SPI driver will do it.
- Add bit(0) for read function as tas2781 will check last bit of address,
to determine operation mode is read (1) or write (0).
- Change switch case to if check in tas2781_hda_playback_hook(),
as it may cause compile problem in clang-19 building.
- Change variable declaration position.
- Change order in if check.
- Remove old hardware id ("TIAS2781") support.
- Remove debug message in runtime suspend and resume.
- Remove regmap.h include in tas2781_spi_fwlib.c.
- Remove MODULE_ in fwlib as this file will work with tas2781_hda_spi.c only.
v4:
- Add old hardware id "TIAS2781" for compatible with old production
- Add 2 devices in struct smi_node tas2781_hda, to compatible with 4 AMPs
v4:
- Add old hardware id "TIAS2781" for compatible with old production
- Add 2 devices in struct smi_node tas2781_hda, to compatible with 4 AMPs
- 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

- 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()

Integrate tas2781 hda spi driver configs for HP (Varcolac). Every tas2781 SPI node was added by serial-multi-instantie.c as a single SPI device. The code support Realtek as the primary codec. Signed-off-by: Baojun Xu <baojun.xu@ti.com> --- v7: - Add new project Gemtree (0x103c8daa) support for tas2781 spi driver. v6: - Remove client in tasdevice_priv struct as it was not used. - Change format for tasdevice_spi_dev_write() in tas2781_hda_spi.c. - Change update bits function to read & write mode, as tas2781 use last bit to mask read & write, it cause regmap_update_bits work not as our expected. - Add element in tas2781_snd_controls, tas2781_prof_ctrl, tas2781_dsp_conf_ctrl, to support second device. Previous version add sound card for first index only. - Change calibration registers address declaire to TASDEVICE_REG() mode. - Add snd_ctl_new1() for second device. - Change format for tas2781_hda_unbind() to fit 79 chars in one line. - Remove client for spi as it was not used. - Remove unused variables. - Remove cur_prog clean in runtime_suspend(). - Remove unused variables. - Add tasdevice_spi_tuning_switch() in runtime_resume. - Remove cur_prog clean in system_resume(). -
