From bcf71917c9ddd6714126e6115bfa26ea482d7afb Mon Sep 17 00:00:00 2001 From: Pierre-Louis Bossart Date: Mon, 15 May 2023 15:10:36 +0800 Subject: soundwire: intel_ace2x: add new_peripheral_assigned callback MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add the abstraction needed to only program the LSDIID registers for the HDaudio extended links. It's perfectly fine to program this register multiple times in case devices lose sync and reattach.
