From ea2cb26a98378b60be8e952eca801130c1da4c73 Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto Date: Wed, 23 Aug 2023 00:19:42 +0000 Subject: ASoC: audio-graph-card2: add comment for format property We don't need to have "format" property on DT any more if CPU/Codec driver has .auto_selectable_formats settings on snd_soc_dai_ops. The sample dtsi doesn't have it. To avoid user confusion, this patch indicates it on comment.
