From 1536a968892aa9095aada4b6d2ed326432cd71c8 Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto Date: Sun, 21 Jul 2013 21:35:52 -0700 Subject: ASoC: add Renesas R-Car core feature Renesas R-Car series sound circuit consists of SSI and its peripheral. But this peripheral circuits are different between R-Car Generation1 (E1/M1/H1) and Generation2 (E2/M2/H2). (Actually, there are many difference in Generation1 chips) Basically, for the future, Renesas R-Car series will use Gen2 style sound circuit, but driver should care Gen1 also. The main differences between Gen1 and Gen2 peripheral are 1) register offset, 2) data path. This patch adds basic (core) feature for R-Car series sound driver as prototype Signed-off-by: Kuninori Morimoto Signed-off-by: Mark Brown --- include/sound/rcar_snd.h | 33 +++++++++++++++++++++++++++++++++ 1 file changed, 33 insertions(+) create mode 100644 include/sound/rcar_snd.h (limited to 'include/sound') diff --git a/include/sound/rcar_snd.h b/include/sound/rcar_snd.h new file mode 100644 index 000000000000..7272b2ea7108 --- /dev/null +++ b/include/sound/rcar_snd.h @@ -0,0 +1,33 @@ +/* + * Renesas R-Car SRU/SCU/SSIU/SSI support + * + * Copyright (C) 2013 Renesas Solutions Corp. + * Kuninori Morimoto + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License version 2 as + * published by the Free Software Foundation. + */ + +#ifndef RCAR_SND_H +#define RCAR_SND_H + +#include + + +#define RSND_BASE_MAX 0 + +struct rsnd_dai_platform_info { + int ssi_id_playback; + int ssi_id_capture; +}; + +struct rcar_snd_info { + u32 flags; + struct rsnd_dai_platform_info *dai_info; + int dai_info_nr; + int (*start)(int id); + int (*stop)(int id); +}; + +#endif -- cgit v1.2.3
