From: Richard Fitzgerald Date: Tue, 3 Dec 2024 10:45:33 +0000 (+0800) Subject: ASoC: cs35l56: Split SoundWire DAI into separate playback and capture X-Git-Tag: v6.14-rc1~111^2~7^2~82^2~1 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=5547e7ca122081d0603d2d7e0fe81a7c551f1e11;p=thirdparty%2Fkernel%2Fstable.git ASoC: cs35l56: Split SoundWire DAI into separate playback and capture This patch splits the SoundWire capture DP into a separate DAI so that it can be independently routed and/or aggregated. It also makes corresponding changes to the SOF SoundWire machine driver. The playback and capture over SoundWire are separate DPs so don't have to route to the same place. They could also be aggregated differently - for example the playback DP could be aggregated with a playback-only DAI on a codec. No production device currently uses the capture path and their topologies do not connect it. So there is no need to change the machine driver match table entries for these. They will simply drop the unused capture DAI. There is one hookup used for a non-production development board that was added by commit 05fe62842804 ("ASoC: Intel: soc-acpi-intel-mtl-match: add acpi match table for cdb35l56-eight-c") This is the only hookup using a topology that connects the SoundWire DP for capture, so this hookup has been changed to include an aggregated endpoint for the capture DAI.
