Before knowing this information, I created another series for a new driver. Link: https://lore.kernel.org/lkml/cover.1701733441.git.soyer@irl.hu/ This series now extends tas2781-hda. The tas2563 is a smart amplifier. Similar to tas2562 but with DSP. Some Lenovo laptops have it to drive the bass speakers. By default, it is in software shutdown state. To make the DSP work it needs a firmware and some calibration data. The latter can be read from the EFI in Lenovo laptops. For the correct configuration it needs additional register data. It captured after running the Windows driver. The firmware can be extracted as TAS2563Firmware.bin from the Windows driver with innoextract. https://download.lenovo.com/consumer/mobiles/h5yd037fbfyy7kd0.exe The driver will search for it as TAS2XXX3870.bin with the Lenovo Yoga 7 14ARB7. The captured registers extracted with TI's regtool: https://github.com/soyersoyer/tas2563rca/raw/main/INT8866RCA2.bin Changes since v1: - fixes were sent as individual patches - rebased onto for-next - adding the missed fixup Gergo Koteles (4): ALSA: hda/tas2781: add ptrs to calibration functions ALSA: hda/tas2781: add configurable global i2c address ALSA: hda/tas2781: add TAS2563 support for 14ARB7 ALSA: hda/tas2781: add fixup for Lenovo 14ARB7 include/sound/tas2781.h | 8 +++ sound/pci/hda/patch_realtek.c | 14 ++++ sound/pci/hda/tas2781_hda_i2c.c | 115 ++++++++++++++++++++++++++---- sound/soc/codecs/tas2781-comlib.c | 15 ++++ 4 files changed, 137 insertions(+), 15 deletions(-) base-commit: 64bf8dec54cfe57f416884a6b3d54c7f4259e93f
