2015-01-02ALSA: es18xx: Remove always NULL parameterLars-Peter Clausen1-8/+2
snd_es18xx_pcm() takes a pointer to a pointer of a PCM where if this parameter is provided the newly allocated PCM is stored. All callers pass NULL though, so remove the parameter. This makes the code a bit cleaner and shorter. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2015-01-02ALSA: es1688: Remove almost always NULL parameterLars-Peter Clausen4-12/+6
snd_es1688_pcm() takes a pointer to a pointer of a PCM where if this parameter is provided the newly allocated PCM is stored. This PCM is also available from the pcm field of the snd_es1688 struct that got passed to the same function. This patch updates all callers which passed a pointer to use that field instead and then removes the parameter from the function. This makes the code a bit shorter and cleaner.

2014-12-30ALSA: pcm: Use __ffs() instead of ffs() in snd_mask_min()Lars-Peter Clausen1-1/+1
The difference between __ffs and ffs is that ffs will return a one based index whereas __ffs will return a zero based index. Furthermore ffs will check if the passed value is zero and return zero in that case, whereas __ffs behavior is undefined if the passed parameter is 0. Since we already check if the mask is 0 before calling ffs and also subtract 1 from the result __ffs is the better choice.

2014-12-30ALSA: Add support for wildcard msbits constraintsLars-Peter Clausen1-1/+12
Currently the msbits constraints requires to specify a specific sample format width for which the constraint should be applied. But often the number of most significant bits is not sample format specific, but rather a absolute limit. E.g. the PCM interface might accept 32-bit and 24-bit samples, but the DAC has a 16-bit resolution and throws away the LSBs. In this case for both 32-bit and 24-bit format msbits should be set to 16. This patch extends snd_pcm_hw_constraint_msbits() so that a wildcard constraint can be setup that is applied for all formats with a sample width larger than the specified msbits. Choosing the wildcard constraint is done by setting the sample width parameter of the function to 0. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2014-12-30ALSA: Fix handling of multiple msbits constraints on the same runtimeLars-Peter Clausen1-1/+1
If the sound card is made up of discrete components, each with their own driver (e.g. like in the ASoC case), we might end up with multiple msbits constraint rules installed. Currently this will result in msbits being set to whatever the last rule set it to. This patch updates the behavior of the rule to choose the minimum (other than zero) of all the installed rules.

Implemented separate stream_tag assignment for input and output streams. According to hda specification stream tag must be unique throughout the input streams group, however an output stream might use a stream tag which is already in use by an input stream. This change is necessary to support HW which provides a total of more than 15 stream DMA engines which with legacy implementation causes an overflow on SDxCTL.STRM field (and the whole SDxCTL register) and as a result usage of Reserved value 0 in the SDxCTL.STRM field which confuses HDA controller.

2014-12-22ASoC: dapm: Simplify fully route card handlingLars-Peter Clausen3-92/+16
For legacy reasons the ASoC framework assumes that a CODEC INPUT or OUTPUT widget that is not explicitly connected to a external source or sink is potentially connected to a source or a sink and hence the framework treats the widget itself as source (for INPUT) or sink (for OUTPUT). For this reason a INPUT or OUTPUT widget that is really not connected needs to be explicitly marked as so. Setting the card's fully_routed flag will cause the ASoC core, once that all widgets and routes have been registered, to go through the list of all widgets and mark all INPUT and OUTPUT that are not externally connected as non-connected. This essentially negates the default behaviour of treating INPUT or OUTPUT widgets without external routes as sources or sinks. This patch takes a different approach while getting the same result. Instead of first marking INPUT and OUTPUT widgets as sinks/sources and then later marking them as non-connected, just never mark them as a sink or a source if the fully_routed flag is set on a card. This requires a lot less code and also results in a slightly faster card initialization since there is no need to iterate over all widgets and check whether the INPUT and OUTPUT widgets are connected or not.
