[alsa-devel] [PATCH v8 7/7] ASoC: hdac_hda: add asoc extension for legacy HDA codec drivers
Pierre-Louis Bossart
pierre-louis.bossart at linux.intel.com
Wed Aug 22 22:25:03 CEST 2018
From: Rakesh Ughreja <rakesh.a.ughreja at intel.com>
This patch adds a kernel module which is used by the legacy HDA
codec drivers as library. This implements hdac_ext_bus_ops to enable
the reuse of legacy HDA codec drivers with ASoC platform drivers.
