From 3b0b441a297e7fe11baab51439a81cd6a336ed64 Mon Sep 17 00:00:00 2001 From: Pierre-Louis Bossart Date: Mon, 29 Apr 2024 00:43:19 +0000 Subject: soundwire: intel_ace2x: use DOAIS and DODS settings from firmware Starting with LNL, the recommendation is to use settings read from DSD properties instead of hard-coding the values. The DOAIS and DODS values are completely-specific to Intel and are stored in a vendor-specific property structure.
