From b3ad31f33982497dbc7a66a9d3013b1ac6985dfe Mon Sep 17 00:00:00 2001 From: Pierre-Louis Bossart Date: Fri, 11 Nov 2022 09:31:28 +0800 Subject: soundwire: intel: start using hw_ops Before introducing new hardware with completely different register spaces and programming sequences, we need to abstract some of the existing routines in hw_ops that will be platform-specific. For now we only use the 'cnl' ops - after the first Intel platform with SoundWire capabilities. Rather than one big intrusive patch, hw_ops are introduced in this patch so show the dependencies between drivers. Follow-up patches will introduce callbacks for debugfs, power and bus management.
