Subject: ASoC: Intel: soc-acpi: quirk topology filename dynamically
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Different topology filenames may be required depending on which SSP is
used, and whether or not digital mics are present.
This patch adds a tplg_quirk_mask and in the case of the SOF driver
adds the relevant configurations.
This is a short-term solution to the ES8336 support issues.
In a long-term solution, we would need an interface where the machine
driver or platform driver have the ability to alter the topology
hard-coded low-level hardware support, e.g. by substituting an
interface for another, or disabling an interface that is not supported
on a given skew.
