Subject: [PATCH v1] ASoc: tas2781: Add Calibration Kcontrols and tas2563 digtial gain for Chromebook
Calibrated data will be set to default after loading DSP config params,
which will cause speaker protection work abnormally. Reload calibrated
data after loading DSP config params.
Signed-off-by: Shenghao Ding <shenghao-ding@...com>
---
v1:
- Changed the copyright year to 2024 in the related files.
- Add CAL_DAT_SZ for calibrated data size.
- Add TAS2563_DVC_LVL for digtial gain kcontrol.
- Add registers for TAS2563 and TAS2781 calibration.
- Add cali_data_restore for regsiter restore after calibration.
- Add is_user_space_calidata to store the flag where the calibrated
from, user space or bin file from driver parsing.
- Add TASDEVICE_RCA_FW_OK to support only register setting bin in the
device.
- Add tas2563_dvc_table for relationship between tas2563 digtial gains
and register values.
- Correct the filename in the header comments of tas2781-comlib.c,
tas2781-lib.c --> tas2781-comlib.c.
- tasdevice_chn_switch for chip switch among multiple chips(tas2563
or tas2781)
- Add loading the calibrated values from user space in
tasdev_load_calibrated_data
- Correct no dsp no work, it can still work in bypass mode.
- Add calibrated register setting for tas2563&tas2781.
- Add mutex into each kcontrol.
- rename tas2781_force_fwload_get, tas2781_force_fwload_put-->
tasdev_force_fwload_get, tasdev_force_fwload_put
- rename tas2781_codec --> tasdev_codec
- define tas2781_snd_control and tas2563_snd_control for volume
- define tas2781_cali_control and tas2563_cali_control for calibration
