[PATCH 7/8] ASoC: Intel: sof_ssp_amp: rename driver and support cs35l41 amplifier

Pierre-Louis Bossart pierre-louis.bossart at linux.intel.com
Tue Mar 1 20:49:02 CET 2022


From: Brent Lu <brent.lu at intel.com>

Add support of CS35L41 amplifier to the machine driver, as well as
the support of HDMI playback and BT offload DAI Link.

Rename the driver to a generic name to support different amplifiers
from different vendors.
