Just like what runtime PM does, it would deactivate and activate pin group depending on whether it's being used or not. And this pinctrl PM might be also beneficial to cpu dai drivers because they might have actual pinctrl so as to sleep their pins and wake them up as needed. To achieve this goal, this patch sets pins to the default state during resume or startup; While during suspend and shutdown, it would set pins to the sleep state. As pinctrl PM would return zero if there is no such pinctrl sleep state settings, this patch would not break current ASoC subsystem directly. [ However, there is still an exception that the patch can not handle, that is, when cpu dai driver does not have pinctrl property but another device has it. (The AUDMUX <-> SSI on Freescale i.MX6 series for example. SSI as a cpu dai doesn't contain pinctrl property while AUDMUX, an Audio Multiplexer, has it). In this case, this kind of cpu dai driver needs to find a way to obtain the pinctrl property as its own, by moving property from AUDMUX to SSI, or creating a pins link/dependency between these two devices, or using a more decent way after we figure it out. ] Signed-off-by: Nicolin Chen Signed-off-by: Mark Brown --- sound/soc/soc-core.c | 33 +++++++++++++++++++++++++++++++++ sound/soc/soc-pcm.c | 11 +++++++++++ 2 files changed, 44 insertions(+) (limited to 'sound') diff --git a/sound/soc/soc-core.c b/sound/soc/soc-core.c index b38e0ee622df..1a4e97773c71 100644 --- a/sound/soc/soc-core.c +++ b/sound/soc/soc-core.c @@ -662,6 +662,8 @@ int snd_soc_suspend(struct device *dev) codec->cache_sync = 1; if (codec->using_regmap) regcache_mark_dirty(codec->control_data); + /* deactivate pins to sleep state */ + pinctrl_pm_select_sleep_state(codec->dev); break; default: dev_dbg(codec->dev, @@ -679,6 +681,9 @@ int snd_soc_suspend(struct device *dev) if (cpu_dai->driver->suspend && cpu_dai->driver->ac97_control) cpu_dai->driver->suspend(cpu_dai); + + /* deactivate pins to sleep state */ + pinctrl_pm_select_sleep_state(cpu_dai->dev); } if (card->suspend_post) @@ -807,6 +812,16 @@ int snd_soc_resume(struct device *dev) if (list_empty(&card->codec_dev_list)) return 0; + /* activate pins from sleep state */ + for (i = 0; i < card->num_rtd; i++) { + struct snd_soc_dai *cpu_dai = card->rtd[i].cpu_dai; + struct snd_soc_dai *codec_dai = card->rtd[i].codec_dai; + if (cpu_dai->active) + pinctrl_pm_select_default_state(cpu_dai->dev); + if (codec_dai->active) + pinctrl_pm_select_default_state(codec_dai->dev); + } + /* AC97 devices might have other drivers hanging off them so * need to resume immediately.

As timer drifts may well be a problem, this was changed in commit b4e82b5b785670b6 to be based on buffer transmission progress, using iprtd->offset and runtime->buffer_size to calculate the amount of data since last period had elapsed. Unfortunately, iprtd->offset counts in bytes, while runtime->buffer_size counts frames, so adding these to find some delta is like comparing apples and oranges, and eventually results in negative delta values every now and then. This is no big harm, because it simply causes snd_pcm_period_elapsed() being called more often than necessary, as negative delta is taken for a large unsigned value by implicit conversion rule. Nonetheless, the calculation is broken, so one would replace the runtime->buffer_size by its equivalent in bytes. But then, there are chances snd_pcm_period_elapsed() is called late, because calculating the moment for the elapsed period into delta is based against the iprtd->last_offset, which is not necessarily the first byte of the period in question, but some random byte which the FIQ handler left us with in r8/r9 by accident. Again, negative impact is low, as there are plenty of periods already prefilled with data, and snd_pcm_period_elapsed() will probably be called latest when the following period is reached. However, the calculation is conceptually broken, and we are best off removing the clever stuff altogether. snd_pcm_period_elapsed() is now simply called once everytime snd_hrtimer_callback() is run, which may not be most accurate, but at least this way we are quite sure we dont miss an end of period. There is not much extra effort wasted by superfluous calls to snd_pcm_period_elapsed(), as the timer frequency closely matches the period size anyway.
