Subject: [alsa-devel] [RFC PATCH 02/12] ASoC: SOF: support alternate list of machines
Date: Mon, 16 Sep 2019 16:42:41 -0500 [thread overview]
Message-ID: <20190916214251.13130-3-pierre-louis.bossart@linux.intel.com> (raw)
In-Reply-To: <20190916214251.13130-1-pierre-louis.bossart@linux.intel.com>
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.
