[alsa-devel] [PATCH] s3c2412-i2s: Fix dai registration
by Heiko Stübner 01 May '12

As s3c2412-i2s is using the s3c_i2sv2 it should call the more specialised s3c_i2sv2_register_dai instead of simply calling snd_soc_register_dai.

by Brian Austin 30 Apr '12

30 Apr '12

This patch adds support for Cirrus Logic CS42L52 Low Power Stereo Codec v2 Changes: Fixes for regcache volatile and CHIPID Add platform data structures for MIC, Charge Pump, MICBIAS levels Add input support for Beep Generator Move L/R Swap into DAPM Use DAPM Routes to hook AIF widgets to DAI's Fix SND_SOC_BIAS cases Use regmap_patch for magic writes at probe Use devm_regmap_init_i2c() Use module_i2c_driver() Signed-off-by: Brian Austin <brian.austin(a)cirrus.com> Signed-off-by: Georgi Vlaev <joe(a)nucleusys.com> --- include/sound/cs42l52.h | 36 ++ sound/soc/codecs/Kconfig | 4 + sound/soc/codecs/Makefile | 2 + sound/soc/codecs/cs42l52.c | 1302 ++++++++++++++++++++++++++++++++++++++++++++ sound/soc/codecs/cs42l52.h | 274 ++++++++++ 5 files changed, 1618 insertions(+), 0 deletions(-) create mode 100644 include/sound/cs42l52.h create mode 100644 sound/soc/codecs/cs42l52.c create mode 100644 sound/soc/codecs/cs42l52.h diff --git a/include/sound/cs42l52.h b/include/sound/cs42l52.h new file mode 100644 index 0000000..4c68955 --- /dev/null +++ b/include/sound/cs42l52.h @@ -0,0 +1,36 @@ +/* + * linux/sound/cs42l52.h -- Platform data for CS42L52 + * + * Copyright (c) 2012 Cirrus Logic Inc. + * + * 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 __CS42L52_H +#define __CS42L52_H + +struct cs42l52_platform_data { + + /* MICBIAS Level.
