From 6bae5ea9498926440ffc883f3dbceb0adc65e492 Mon Sep 17 00:00:00 2001 From: Rakesh Ughreja Date: Wed, 22 Aug 2018 15:25:03 -0500 Subject: ASoC: hdac_hda: add asoc extension for legacy HDA codec drivers 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.
