From 2020dddd67c1884ea7cb9891b36aac7ff5e73038 Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto Date: Tue, 8 Dec 2015 00:10:59 +0000 Subject: [PATCH] ARM: shmobile: r8a7778: tidyup #sound-dai-cells settings Renesas sound driver needs #sound-dai-cells settings, but, this usage is a little bit confusable. It came from ALSA SoC historical reasons. The sound DAI naming method is different between Single/Multi DAI in the ALSA framework, and it is used for sound card matching. And this #sound-dai-cells has relationship to it. Current SoC dtsi has #sound-dai-cells = <1> as default settings (= it is assuming that board/platform has multi DAI), and board/platform side needs to overwrite it if board/platform was single DAI. This style is more confusable for users. This patch removes SoC side default settings, and force to set it by board/platform side.
