From e829b6e5d942526824d51021ea3d7a6cf7c15064 Mon Sep 17 00:00:00 2001 From: Pierre-Louis Bossart Date: Mon, 16 Sep 2019 16:42:41 -0500 Subject: [PATCH] ASoC: SOF: support alternate list of machines For cases where an interface can be pin-muxed, we need to assess at probe time which configuration should be used. In cases such as SoundWire, we need to maintain an alternate list of machines and walk through them when the primary detection based on ACPI _HID fails.
