From 955927873d82c5127e31e618703d804033a93e4f Mon Sep 17 00:00:00 2001 From: Sameer Pujar Date: Mon, 8 Aug 2022 10:57:31 +0530 Subject: [PATCH] ASoC: dt-bindings: Add sample format conversion 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 audio-graph-card based bindings.
