From 3f0c43e60d19e1c126ddad47c77a5e1036e52378 Mon Sep 17 00:00:00 2001 From: Sylwester Nawrocki Date: Mon, 12 Feb 2018 17:15:38 +0100 Subject: [PATCH] ASoC: samsung: Add missing #sound-dai-cells property documentation The #sound-dai-cells property might be helpful in selecting primary or secondary CPU DAI and it's already present in i2s nodes for some exynos SoCs so let's add it to the DT binding documentation.
