From 047e8dd968015d6fbcae4fded5313c741952ef68 Mon Sep 17 00:00:00 2001 From: Fabio Estevam Date: Fri, 14 Nov 2014 02:14:47 -0200 Subject: ASoC: sgtl5000: Fix SMALL_POP bit definition commit c251ea7bd7a04f1f2575467e0de76e803cf59149 upstream On a mx28evk with a sgtl5000 codec we notice a loud 'click' sound to happen 5 seconds after the end of a playback. The SMALL_POP bit should fix this, but its definition is incorrect: according to the sgtl5000 manual it is bit 0 of CHIP_REF_CTRL register, not bit 1. Fix the definition accordingly and enable the bit as intended per the code comment. After applying this change, no loud 'click' sound is heard after playback Signed-off-by: Fabio Estevam Signed-off-by: Mark Brown Cc: stable@vger.kernel.org --- sound/soc/codecs/sgtl5000.c | 3 +-- sound/soc/codecs/sgtl5000.h | 2 +- 2 files changed, 2 insertions(+), 3 deletions(-) diff --git a/sound/soc/codecs/sgtl5000.c b/sound/soc/codecs/sgtl5000.c index 13b201771d5f..07fe76c8cc8d 100644 --- a/sound/soc/codecs/sgtl5000.c +++ b/sound/soc/codecs/sgtl5000.c @@ -1323,8 +1323,7 @@ static int sgtl5000_probe(struct snd_soc_codec *codec) /* enable small pop, introduce 400ms delay in turning off */ snd_soc_update_bits(codec, SGTL5000_CHIP_REF_CTRL, - SGTL5000_SMALL_POP, - SGTL5000_SMALL_POP); + SGTL5000_SMALL_POP, 1); /* disable short cut detector */ snd_soc_write(codec, SGTL5000_CHIP_SHORT_CTRL, 0); diff --git a/sound/soc/codecs/sgtl5000.h b/sound/soc/codecs/sgtl5000.h index d3a68bbfea00..0bd6e1cd8200 100644 --- a/sound/soc/codecs/sgtl5000.h +++ b/sound/soc/codecs/sgtl5000.h @@ -275,7 +275,7 @@ #define SGTL5000_BIAS_CTRL_MASK 0x000e #define SGTL5000_BIAS_CTRL_SHIFT 1 #define SGTL5000_BIAS_CTRL_WIDTH 3 -#define SGTL5000_SMALL_POP 0x0001 +#define SGTL5000_SMALL_POP 0 /* * SGTL5000_CHIP_MIC_CTRL -- cgit v1.2.3
