Since 2025, the firmware for tas2781 has been added more audio acoustic features, such as non-linear compensation, advanced battery guard, rattle-noise suppression, etc. The version was divided into two different series. Both series have a slight change on the calibrated data storage addresses, which becames flexible instead of fixed. In order to support new firwmares in time, the code have some related upgrades. Signed-off-by: Shenghao Ding <shenghao-ding@ti.com> --- v2: - revise the subject and description. v1: - Add updating calibration addresses code into tas2781_apply_calib in case of Alpha and Beta firmware. --- sound/pci/hda/tas2781_hda_i2c.c | 30 ++++++++++++++++++++---------- 1 file changed, 20 insertions(+), 10 deletions(-)
