Subject: [PATCH 5/7] ASoC: Intel: avs: Account for UID of ACPI device
Date: Fri, 19 May 2023 22:17:09 +0200	[thread overview]
Message-ID: <20230519201711.4073845-6-amadeuszx.slawinski@linux.intel.com> (raw)
In-Reply-To: <20230519201711.4073845-1-amadeuszx.slawinski@linux.intel.com>

From: Cezary Rojewski <cezary.rojewski@intel.com>

Configurations with multiple codecs attached to the platform are
supported but only if each from the set is different. Add new field
representing the 'Unique ID' so that codecs that share Vendor and Part
IDs can be differentiated and thus enabling support for such
configurations.
