[alsa-devel] [PATCH v3 0/2] ALSA: jack: Refactoring for jack kctls
by Jie Yang 25 Mar '15

25 Mar '15

Currently only hda will create kctls for hda jacks, for asoc, people may need create jack kctls in specific driver. Here we are introducing kctls for each jack, by creating kctls and add them to jack controls list (considering exist of combo jack). At the same time, we will report events for each control in the list. With this implement, we are no longer need hda jack specific kctls, so here also remove jack kctls for hda. Changes in v3: 1. replace bit index with bit mask in jack_kctl; 2. add exception for SND_JACK_HEADSET and SND_JACK_AVOUT, only create one jack kctl for these two combo jacks, respectively. 3. add NULL check, mem kfree, and fix some potential risk. Change in v2: 1. define jack_kctl struct, and put jack kctl related stuff there; 2. add a patch to remove the existing controls for HDA jack.

[alsa-devel] [PATCH v3] ASoC: davinci-mcasp: Set rule constraints if implicit BCLK divider is used
by Jyri Sarha 24 Mar '15

24 Mar '15

Set rule constraints to allow only combinations of sample-rate, sample-format, and channels counts that can be played/captured with reasonable sample-rate accuracy. The logic with tdm-slots and serializers (=i2s data wires) goes like this: The first wire will take all channels up to number of tdm-slots, before following wires (if any) are used. If the first wire is used fully, the remaining wires share the same clocks and the divider can be calculated for the first wire. Also, takes the number of tdm-slots into account when implicitly selecting the BLCK divider. Signed-off-by: Jyri Sarha <jsarha(a)ti.com> --- Previous version of the patch: http://mailman.alsa-project.org/pipermail/alsa-devel/2015-March/089319.html Since v2 I changed the SNDRV_PCM_HW_PARAM_SAMPLE_BITS rule in the to SNDRV_PCM_HW_PARAM_FORMAT rule. Somehow the constraints with a SNDRV_PCM_HW_PARAM_SAMPLE_BITS rule using snd_interval_list() converged to an empty set when ever I tried to play a format that could not pass the rule with any channel count or rate, resulting all too familiar assertion in alsa-lib. However, the direct tampering with SNDRV_PCM_HW_PARAM_FORMAT mask appears to work as it should. In addition to SAMPLE_BITS- to FORMAT-rule change I optimized the rate rule a bit so that it does not try the rates that are outside current range. According to my tests this does not affect the behavior in any other way but slightly speeds up the decision making. sound/soc/davinci/davinci-mcasp.c | 207 ++++++++++++++++++++++++++++++++++++-- 1 file changed, 197 insertions(+), 10 deletions(-) diff --git a/sound/soc/davinci/davinci-mcasp.c b/sound/soc/davinci/davinci-mcasp.c index d40b392..76156d18 100644 --- a/sound/soc/davinci/davinci-mcasp.c +++ b/sound/soc/davinci/davinci-mcasp.c @@ -27,6 +27,7 @@ #include <linux/of_platform.h> #include <linux/of_device.h> #include <linux/platform_data/davinci_asp.h> +#include <linux/math64.h> #include <sound/asoundef.h> #include <sound/core.h> @@ -65,6 +66,11 @@ struct davinci_mcasp_context { bool pm_state;
