Subject: [PATCH 1/2] ASoC: dt-bindings: Add sample format conversion
Date: Wed, 27 Jul 2022 19:56:22 +0530 [thread overview]
Message-ID: <1658931983-31647-2-git-send-email-spujar@nvidia.com> (raw)
In-Reply-To: <1658931983-31647-1-git-send-email-spujar@nvidia.com>
Presently "convert-channels" and "convert-rate" DT bindings are available
for channel and rate fixups respectively.
Similarly add "convert-sample-format" binding to fixup DAI sample format
as well. This is added to simple-card and audio-graph based sound cards.
