[alsa-devel] [Patch V6 00/10] ASoC: QCOM: Add support for ipq806x SOC
by Kenneth Westfield 25 Feb '15

25 Feb '15

From: Kenneth Westfield <kwestfie(a)codeaurora.org> This patch series adds support for I2S audio playback on the Storm board, which contains a Qualcomm Technologies ipq806x SOC and a Maxim max98357a DAC/amp. The ipq806x SOC has audio-related hardware blocks in its low-power audio subsystem (or LPASS). One of the relevant blocks in the LPASS is its low-power audio interface (or LPAIF). This contains an MI2S port, which is what these drivers are configured to use. The LPAIF also contains a DMA engine that is dedicated to moving audio samples into the transmit FIFO of the MI2S port. One bus from the MI2S port of the SOC is connected to the DAC/amp for stereo playback. This bus is configured so that the SOC is bus master and consists of DATA, LRCLK, and BCLK. The DAC/amp does not need MCLK to operate. In addition, a single GPIO pin from the SOC is connected to the same DAC/amp, which gives enable/disable control over the DAC/amp. The specific drivers added are: * a CPU DAI driver for controlling the MI2S port * a platform driver for controlling the LPAIF DMA engine * a machine driver that instantiates a dai-link for playback The LPASS also contains clocks that need to be controlled. Those drivers have been submitted as a separate patch series: [PATCH v3 0/8] qcom audio clock control drivers http://lkml.org/lkml/2015/1/19/656 Even though the ipq806x LPASS does not contain an audio DSP, other SOCs do have one. For those SOCs, the audio DSP typically controls the hardware blocks in the LPASS. Hence, different CPU DAI driver(s) would need to be used in order to facilitate audio with the DSP. As such, the LPASS DT contains an adsp subnode, which is disabled for this SOC. The same subnode should be enabled and populated for other SOCs that do contain an audio DSP. Not using the audio DSP would require different CPU DAI driver(s), in addition to possible bootloader and/or firmware changes. Corresponding additions to the device tree for the ipq806x SOC and its documentation has also been added. Also, as this is a new directory, the MAINTAINERS file has been updated as well. = Changes since V5 [Patch V5 00/12] ASoC: QCOM: Add support for ipq806x SOC http://mailman.alsa-project.org/pipermail/alsa-devel/2015-February/087832.h… * Correctly use Storm as the build target label and DT binding label. * Added audio DSP sub-node to the LPASS device tree, disabled for this SOC. * Added logic to CPU DAI driver to fail the probe() if a DSP is present. * Use the standard naming convention for the DAI link properties. * General code cleanup. = Changes since V4 [Patch V4 00/10] ASoC: QCOM: Add support for ipq806x SOC http://mailman.alsa-project.org/pipermail/alsa-devel/2015-February/087499.h… * Replaced simple-card with a machine driver to resolve the system clock configuration, rather than having the CPU DAI driver do it. * Added header files to avoid indirect header dependencies and implicit forward declarations. * Tweaked the ISR to match the conventions of the surrounding code. * Removed the usage of the low-power memory as it is not needed. * Removed the use of the DRV_NAME constant. * Added explicit dependency on gpiolib for the codec driver. * Moved the MODULE_DEVICE_TABLE macro inside the CONFIG_OF conditional. * Modified the documentation to reflect the changes. * General code cleanup. = Changes since V3 [Patch V3 00/10] ASoC: QCOM: Add support for ipq806x SOC http://mailman.alsa-project.org/pipermail/alsa-devel/2014-December/085694.h… * Placed the content of the inline functions into the callbacks. * Replaced use of readl/writel register access functions with regmap access functions. Notable exception is the ISR, which uses ioread32/iowrite32. * Rearranged the sequencing of the hardware block enables to fit within the ASoC framework callbacks, while remaining functional. REQ 1: The hardware requires the enable sequence to be: LPAIF-DMA[enable],then LPAIF-MI2S[enable], then DAC-GPIO[enable] REQ 2: The hardware requires the disable sequence to be: DAC-GPIO[disable], then LPAIF-MI2S[disable] * Corrected the implementation of the pointer callback. * Utilize the LPM to buffer audio samples, rather than memory external to LPASS. * Corrected the interrupt clearing in the ISR. * Implemented a default system clock (defined by the simple-card DT node), and optional LPASS DT node modifiers that can alter the system clock in order to expand the range of available bit clock frequencies. * Addressed all of the remaining issues raised by Mark Brown. * General code cleanup. = Changes since V2 [Patch v2 00/11] ASoC: QCOM: Add support for ipq806x SOC http://mailman.alsa-project.org/pipermail/alsa-devel/2014-December/085186.h… * Removed the PCM platform driver from the DTS platform and tied it to the CPU DAI driver. * Changed I2S pinctrl to use generic naming convention and moved control to CPU DAI driver. It should be controlled now by soc-core's pinctrl_pm_* functionality. * Added stub DAPM support in codec driver. As the DAC GPIO needs to be enabled last when starting playback, and disabled first when stopping playback, it seems as though the trigger function may be the place for this. Suggestions are welcome for a better place to put this. * Removed machine driver and tied DAI drivers to simple-audio-card. * Packaged the build files and Maxim codec files together in one change. * Removed QCOM as vendor from Maxim code and documentation. * Separated the SOC and board definitions into the correct DTS files. * Update device tree documentation to reflect changes. * General code cleanup. = Changes since V1 [PATCH 0/9] ASoC: QCOM: Add support for ipq806x SOC http://mailman.alsa-project.org/pipermail/alsa-devel/2014-November/084322.h… * Remove the native LPAIF driver, and move its functionality to the CPU DAI driver. * Add a codec driver to manage the pins going to the external DAC (previously managed by the machine driver). * Use devm_* and dev_* where possible. * ISR only handles relevant DMA channel now. * Update device tree documentation to reflect changes. * General code cleanup.

It doesn't help much without knowing what amixer is trying to do. > I think I have written the node according to the documentation, but > probably I miss something. Looking at sound/soc/codecs/tlv320aic23.c: static const struct snd_soc_dapm_route tlv320aic23_intercon[] = { /* Output Mixer */ {"Output Mixer", "Line Bypass Switch", "Line Input"}, {"Output Mixer", "Playback Switch", "DAC"}, {"Output Mixer", "Mic Sidetone Switch", "Mic Input"}, /* Outputs */ {"RHPOUT", NULL, "Output Mixer"}, {"LHPOUT", NULL, "Output Mixer"}, {"LOUT", NULL, "Output Mixer"}, {"ROUT", NULL, "Output Mixer"}, /* Inputs */ {"Line Input", "NULL", "LLINEIN"}, {"Line Input", "NULL", "RLINEIN"}, {"Mic Input", "NULL", "MICIN"}, /* input mux */ {"Capture Source", "Line", "Line Input"}, {"Capture Source", "Mic", "Mic Input"}, {"ADC", NULL, "Capture Source"}, }; The lines with the failing routes really look suspicious, i.e. there is strings "NULL" where I'd expect plain NULL. What happens if you amend the three lines and replace the "NULL" with NULL? Sebastian

OK, then try to pass power_save_controller=0 option to snd-hda-intel module. It might be that the controller gets screwed up by some reason by power-saving. If this still doesn't help, we need more logs. Build the kernel with tracing support, and get the HD-audio verb traces as Documentation/sound/alsa/HD-Audio.txt, section Tracepoints. Takashi

[alsa-devel] [PATCH v4] ASoC: rt286: add jack detection disable with NULL jack passed
by Jie Yang 24 Feb '15

24 Feb '15

Some platforms, e.g. WSB, don't need jack detection when system is in Suspend, for power save reason. Here add headphone/mic jack detection disable feature with NULL jack passed in, when disabled, it will disable interrupt, and disable LDO1, which is used for jack detection when headphone is plugged in.

[alsa-devel] No sound and systemd journal filling when inserting headphones when power-saving is enabled
by Dang Sananikone 24 Feb '15

24 Feb '15

Hi, I previously posted in alsa user mailing list about a problem I was facing with having no sound and the systemd journal filling when using headphones: http://article.gmane.org/gmane.linux.alsa.user/38948 I subsequently realised that I had enabled power-saving a few weeks ago and it was this power-saving that was causing the problem. My response to myself is here: http://article.gmane.org/gmane.linux.alsa.user/38953 I am now satisfied that disabling power-saving has resolved my issue, but there has been a suggestion that I report this issue, so here it is. Apologies if this is the wrong place (this is my first time on the alsa mailing list). Let me know if you want me to create a bug ticket and where it should be created (the bug tracker URL link in the alsa project page is not working).

[alsa-devel] [PATCH 0/20] ASoC: rsnd: add Synchronous SRC and U/O error salvage support
by Kuninori Morimoto 24 Feb '15

24 Feb '15

Hi Mark. These patches adds [1] Synchronous SRC, [2] under/over run error salvage support to Renesas sound driver. 1) - 16) : prepare cleanup/tidyup for 17) - 19) 17) : Synchronous SRC 18)- 19) : salvage support for under/over run error 20) : cleanup for 18) - 19) Current Renesas sound can use Asynchronous/Synchronous sampling rate convert. Asynchronous sampling rate convert is already supported on upstream. ("feature" is supported, "DT" bindings is not yet supported) 17) adds Synchronous sampling rate convert. Renesas sound has HW bug (?) which switches L/R channel if under/over run error had occurred. 18) - 19) adds salvage supported for it. 20) is cleanup patch which is based on 18)-19) patch Kuninori Morimoto (20): 1. ASoC: rsnd: add .fallback callback 2. ASoC: rsnd: add callback status check method 3. ASoC: rsnd: rsnd_src_ssiu_stop() stops SSIU compulsorily 4. ASoC: rsnd: tidyup PIO/DMA mode settings method 5.

[alsa-devel] [PATCH 1/2] ASoC: core: Add extra dapm properties for Device Tree
by Nicolin Chen 24 Feb '15

24 Feb '15

The current helper functions, snd_soc_of_parse_audio_simple_widgets() and snd_soc_of_parse_audio_routing(), set dapm_widgets and dapm_routes without caring if they are already set by using build-in widgets and routes in the card driver. So there could be one of them, build-in one or Device Tree one, overrided by the other depending on which one was assigned later. This patch adds an extra pair of dapm_widgets and dapm_routes for DT use only so as to prevent unexpected overriding.

[alsa-devel] [PATCH 0/2] ASoC: pcm512x: Add knobs to allow and control overclocking
by Peter Rosin 24 Feb '15

24 Feb '15

From: Peter Rosin <peda(a)axentia.se> Hi! I wasn't sure if I should add Documentation/* for these sysfs knobs or not? A lot of knobs do not seem to have docs (no specific example, just a gut feeling). And I'm not sure how I should name the doc-file since the pcm512x driver handles devices connected with both i2c and spi. And what KernelVersion should I enter? That depends... So, this isn't perfect, suggestions welcome. The first patch is a preparatory patch that makes 2/2 slightly simpler. I can fold them together if that's desired. Or I could split 2/2 up in three logical patches, one for each of the independent PLL/DSP/DAC knobs. Another "feature" that one might want, is that attempts to change the overclocking should fail with EBUSY when the device is already in use. But I haven't invested enough time to find out how I should determine when to fail, so for this version the driver accepts the change but doesn't enforce the new limit until the clock rates are recalculated. Cheers, Peter Peter Rosin (2): ASoC: pcm512x: Rearrange to not repeat dacsrc_rate / dac_div ASoC: pcm512x: Allow independently overclocking PLL, DAC and DSP Documentation/ABI/testing/sysfs-i2c-pcm512x | 35 +++++ sound/soc/codecs/pcm512x.c | 189 ++++++++++++++++++++++++--- 2 files changed, 205 insertions(+), 19 deletions(-) create mode 100644 Documentation/ABI/testing/sysfs-i2c-pcm512x -- 1.7.10.4
