From 1e76de2e5dfeff17f13afe8146449fec3f5b69f7 Mon Sep 17 00:00:00 2001 From: Pierre-Louis Bossart Date: Tue, 14 Mar 2023 09:54:03 +0800 Subject: soundwire: intel: add abstraction for cmdsync check If we add one more callback, we can have common bank switch sequences between old and new hardware: the only difference is where the CMDSYNC register is located.
