Subject: [PATCH 00/16] ALSA: hda/tas2781: Add tas2563 support

The tas2781-hda driver can be modified to support tas2563 as well.
Before knowing this information, I created another series for a
new driver.
https://lore.kernel.org/lkml/cover.1701733441.git.soyer@irl.hu/

This series now extends tas2781-hda, addresses differences and
fixes various bugs.

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 14ARB7.
The captured registers extracted with TI's regtool:
