From 9420a5205c8f9a7a7052c36deb3884a18e632644 Mon Sep 17 00:00:00 2001 From: Aaron Durbin Date: Tue, 17 Nov 2015 16:31:00 -0600 Subject: lib: NHLT ACPI table support Intel's SST (Smart Sound Technology) employs audio support which may not consist of HDA. In order to define the topology of the audio devices (mics, amps, codecs) connected to the platform a NHLT specification was created to pass this information from the firmware to the OS/userland. BUG=chrome-os-partner:44481 BRANCH=None TEST=Tested on glados. Audio does get emitted and some mic recording works.
