Subject: [PATCH 02/20] ASoC: soc-acpi: add information on I2S/TDM link mask
Date: Tue,  8 Mar 2022 13:25:52 -0600	[thread overview]
Message-ID: <20220308192610.392950-3-pierre-louis.bossart@linux.intel.com> (raw)
In-Reply-To: <20220308192610.392950-1-pierre-louis.bossart@linux.intel.com>

The platform driver may have information on which I2S/TDM link(s) to
enable in the machine driver. In the case of Intel devices, this may
be extracted from NHLT tables in platform firmware. This link
information is necessary to make sure machine driver and topology are
aligned.
