Subject: [PATCH v2 2/3] ASoC: dt-bindings: Add sample format conversion
Date: Mon, 1 Aug 2022 21:37:31 +0530 [thread overview]
Message-ID: <1659370052-18966-3-git-send-email-spujar@nvidia.com> (raw)
In-Reply-To: <1659370052-18966-1-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.
