From: Jarkko Nikula Date: Fri, 5 Nov 2010 18:35:21 +0000 (+0200) Subject: ASoC: Move pop time from DAPM context to sound card X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3a45b8672d3f8542e430e7a5c7366ec9bdded054;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git ASoC: Move pop time from DAPM context to sound card Based on discussion the dapm_pop_time in debugsfs should be per card rather than per device. Single pop time value for entire card is cleaner when the DAPM sequencing is extended to cross-device paths. debugfs/asoc/{card->name}/{codec dir}/dapm_pop_time -> debugfs/asoc/{card->name}/dapm_pop_time Signed-off-by: Jarkko Nikula Signed-off-by: Mark Brown --- diff --git a/include/sound/soc-dapm.h b/include/sound/soc-dapm.h index 5881876e8f5..78d3560fa25 100644 --- a/include/sound/soc-dapm.h +++ b/include/sound/soc-dapm.h @@ -469,7 +469,6 @@ struct snd_soc_dapm_widget { /* DAPM context */ struct snd_soc_dapm_context { - u32 pop_time; struct list_head widgets; struct list_head paths; enum snd_soc_bias_level bias_level; @@ -479,6 +478,7 @@ struct snd_soc_dapm_context { struct device *dev; /* from parent - for debug */ struct snd_soc_codec *codec; /* parent codec */ + struct snd_soc_card *card; /* parent card */ #ifdef CONFIG_DEBUG_FS struct dentry *debugfs_dapm; #endif diff --git a/include/sound/soc.h b/include/sound/soc.h index 95ce0ddd36d..5d3954774ad 100644 --- a/include/sound/soc.h +++ b/include/sound/soc.h @@ -457,7 +457,6 @@ struct snd_soc_codec { #ifdef CONFIG_DEBUG_FS struct dentry *debugfs_codec_root; struct dentry *debugfs_reg; - struct dentry *debugfs_pop_time; struct dentry *debugfs_dapm; #endif }; @@ -592,7 +591,9 @@ struct snd_soc_card { #ifdef CONFIG_DEBUG_FS struct dentry *debugfs_card_root; + struct dentry *debugfs_pop_time; #endif + u32 pop_time; }; /* SoC machine DAI configuration, glues a codec and cpu DAI together */ diff --git a/sound/soc/codecs/cx20442.c b/sound/soc/codecs/cx20442.c index 11beb1a77c4..a9521acad99 100644 --- a/sound/soc/codecs/cx20442.c +++ b/sound/soc/codecs/cx20442.c @@ -264,7 +264,7 @@ static void v253_close(struct tty_struct *tty) /* Prevent the codec driver from further accessing the modem */ codec->hw_write = NULL; cx20442->control_data = NULL; - codec->dapm.pop_time = 0; + codec->card->pop_time = 0; } /* Line discipline .hangup() */ @@ -292,7 +292,7 @@ static void v253_receive(struct tty_struct *tty, /* Set up codec driver access to modem controls */ cx20442->control_data = tty; codec->hw_write = (hw_write_t)tty->ops->write; - codec->dapm.pop_time = 1; + codec->card->pop_time = 1; } } @@ -349,7 +349,7 @@ static int cx20442_codec_probe(struct snd_soc_codec *codec) cx20442->control_data = NULL; codec->hw_write = NULL; - codec->dapm.pop_time = 0; + codec->card->pop_time = 0; return 0; } diff --git a/sound/soc/soc-core.c b/sound/soc/soc-core.c index 57e5d7bfb13..f030521c48d 100644 --- a/sound/soc/soc-core.c +++ b/sound/soc/soc-core.c @@ -255,13 +255,6 @@ static void soc_init_codec_debugfs(struct snd_soc_codec *codec) printk(KERN_WARNING "ASoC: Failed to create codec register debugfs file\n"); - codec->debugfs_pop_time = debugfs_create_u32("dapm_pop_time", 0644, - codec->debugfs_codec_root, - &codec->dapm.pop_time); - if (!codec->debugfs_pop_time) - printk(KERN_WARNING - "Failed to create pop time debugfs file\n"); - codec->dapm.debugfs_dapm = debugfs_create_dir("dapm", codec->debugfs_codec_root); if (!codec->dapm.debugfs_dapm) @@ -380,9 +373,18 @@ static void soc_init_card_debugfs(struct snd_soc_card *card) { card->debugfs_card_root = debugfs_create_dir(card->name, debugfs_root); - if (!card->debugfs_card_root) + if (!card->debugfs_card_root) { dev_warn(card->dev, "ASoC: Failed to create codec debugfs directory\n"); + return; + } + + card->debugfs_pop_time = debugfs_create_u32("dapm_pop_time", 0644, + card->debugfs_card_root, + &card->pop_time); + if (!card->debugfs_pop_time) + dev_warn(card->dev, + "Failed to create pop time debugfs file\n"); } static void soc_cleanup_card_debugfs(struct snd_soc_card *card) @@ -1426,6 +1428,7 @@ static int soc_probe_dai_link(struct snd_soc_card *card, int num) /* probe the CODEC */ if (!codec->probed) { + codec->dapm.card = card; if (codec->driver->probe) { ret = codec->driver->probe(codec); if (ret < 0) { diff --git a/sound/soc/soc-dapm.c b/sound/soc/soc-dapm.c index b8f653eaffa..960790cc6fb 100644 --- a/sound/soc/soc-dapm.c +++ b/sound/soc/soc-dapm.c @@ -293,6 +293,7 @@ static int dapm_update_bits(struct snd_soc_dapm_widget *widget) unsigned int old, new; struct snd_soc_codec *codec = widget->codec; struct snd_soc_dapm_context *dapm = widget->dapm; + struct snd_soc_card *card = dapm->card; /* check for valid widgets */ if (widget->reg < 0 || widget->id == snd_soc_dapm_input || @@ -312,10 +313,10 @@ static int dapm_update_bits(struct snd_soc_dapm_widget *widget) change = old != new; if (change) { - pop_dbg(dapm->pop_time, "pop test %s : %s in %d ms\n", + pop_dbg(card->pop_time, "pop test %s : %s in %d ms\n", widget->name, widget->power ?
