Subject: [PATCH 429/429] ASoC: soc-acpi: add information on I2S/TDM link mask

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.
