| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If none of the components (CODEC or CPU DAI) sets a maximum sample rate we'll end up with the rate_max field of the runtime hardware set to 0. (Note that it is still possible for the components to constrain the supported sample rates using other methods, e.g. setting a list constraint) If rate_max is 0 this means that the sound card doesn't support any rates at all, which is not the desired result. So initialize rate_max to UINT_MAX. For symmetry reasons also set rate_min to 0. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Mark Brown <broonie@linaro.org>

So here's a use case might be broken by this mechanism: aplay -Dhw:0 44100.wav 48000.wav 32000.wav In this case, we call soc_pcm_open()->soc_pcm_hw_params()->soc_pcm_hw_free() ->soc_pcm_hw_params()->soc_pcm_hw_free()->soc_pcm_close() in order. As we only clear parameters in soc_pcm_close(). The parameters would be remained in the system even if the playback of 44100.wav is finished. Thus, this patch is trying to move parameters cleaning into hw_free() so that the system can continue to serve this kind of use case. Also, since we set them in hw_params(), it should be better to clear them in hw_free() for symmetry. Signed-off-by: Nicolin Chen <b42378@freescale.com> Signed-off-by: Mark Brown <broonie@linaro.org>

So if we let them capture a mono stream while playing a stereo stream, there might be a problem occur to one of these two streams: double paced or slowed down. In soc-pcm.c, we have soc_pcm_apply_symmetry() to apply the rate symmetry. But we don't have one for channels. Likewise, we can treat symmetric_rate as a solution for those SoCs or CODECs which can not handle asymmetrical LRCLK. But it's also impossible for them to handle asymmetrical BCLK. And accodring to BCLK = LRCLK * channel number * slot size(fixed or sample bits), sample bits might also be a problem if they are not using a fixed slot size. Thus, this patch applys symmetry for channels and sample bits. Meanwhile, there might be a race between two substreams if starting simultaneously. Previously, we only added warning to compalin but still using conservative way to let it carry on. However, this patch rejects the second stream with any unmatched parameter to make sure the first existing stream won't be broken.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | snd_pcm_limit_hw_rates() will initialize the minimum and maximum sample rate for the PCM stream based on the rates specified in the rates field. Since we call snd_pcm_limit_hw_rates() after soc_pcm_init_runtime_hw() it will essentially overwrite the min and max rate set in soc_pcm_init_runtime_hw(). This may cause the minimum or maximum rate to be set to a value outside the range of one of the components if one of the components sets either SNDRV_PCM_RATE_CONTINUOUS or SNDRV_PCM_RATE_KNOT and the other component specified a discrete rate via SNDRV_PCM_RATE_[0-9]* that is outside of the first component's rate range. To fix this first calculate the minimum and maximum rates using snd_pcm_limit_hw_rates() and then on top of that apply the contraints specified in the snd_soc_pcm_stream structs.

* ASoC: Add pinctrl PM to components of active DAIsNicolin Chen2013-11-041-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It's quite popular that more drivers are using pinctrl PM, for example: (Documentation/devicetree/bindings/arm/primecell.txt). 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 <b42378@freescale.com> Signed-off-by: Mark Brown <broonie@linaro.org>
