[alsa-devel] [PATCH 0/x][RFC] ASoC: replace codec/platform to component
by Kuninori Morimoto 12 Feb '18

12 Feb '18

Hi Mark Finally, all prepare patch-set were accepted. These are [RFC] of codec/platform replace to component patch-set. It will be almost 200 patches in total. Thus, to avoid patch bomb (in case of rejection), I pickuped few patches and post these as [RFC]. Main is replacing codec/platform to component xxx_codec_xxx() -> xxx_component_xxx() xxx_platform_xxx() -> xxx_component_xxx() Note1 is that it is using devm_ version register function, and removed unregister from .remove (sometimes, removes .remove function itself) - snd_soc_register_xxx() + devm_snd_soc_register_component() ... - snd_soc_unregister_xxx() Note2 is that rtd->platform will be removed, thus it will be replaced to snd_soc_rtdcom_lookup() with driver name - rtd->platform + snd_soc_rtdcom_lookup(rtd, DRV_NAME) Note3 is that codec driver needs to have some flags which is needed for Codec -static const struct snd_soc_codec_driver xxx_codec; +static const struct snd_soc_component_driver xxx_codec = { + .idle_bias_on = 1, + .pmdown_time = 1, + .endianness = 1, + .non_legacy_dai_naming = 1, +}; here, .idle_bias_on was originally .idle_bias_off .pmdown_time was originally .ignore_pmdown_time .endianness is needed for Codec endianness check .non_legacy_dai_naming is needed for Codec DAI name matching Note4 is that some driver is controlling CPU/Platform in one driver as 2 component. Now we can merge these into one component. - snd_soc_register_platform(xxx) // for Platform - snd_soc_register_component(xxx) // for CPU + snd_soc_register_component(xxx) // for CPU/Platform Note4 is that [1/x] patch which removes (!rtd->platform) check from soc-core is needed for all platforms. This check is no longer needed for component version. If these [RFC] were OK, I will post all replacement patch-set. I think good timing to posting is around next -rc1 or merge-window About removing all unneeded codec/platform patch-set, when is good timing ? +1 version: includes replacement patch-set +2 version: includes remove patch-set or +1 version: includes both replacement/remove patch-set Best regards --- Kuninori Morimoto

[alsa-devel] [RESEND PATCH v2 00/15] ASoC: qcom: Add support to QDSP6 based audio
by srinivas.kandagatla＠linaro.org 07 Feb '18

07 Feb '18

From: Srinivas Kandagatla <srinivas.kandagatla(a)linaro.org> This patchset aims to provide a very basic version of QCOM DSP based audio support which is available in downstream andriod kernels. This patchset only support Digital audio based for HDMI-RX and will add support to other features as we move on. QDSP has both static and dynamic modules. static modules like AFE (Audio FrontEnd), ADM (Audio Device Manager), ASM(Audio Stream Manager) and CORE to provide this audio services. All these services use APR (Asynchronous Packet Router) protocol via smd/glink transport to communicate with Application processor. More details on each module is availble in there respective patch. This patchset is tested on DB820c, with HDMI audio playback on top of mainline, also tested slimbus analog audio using wcd9355 with an additional small patch.

[alsa-devel] [PATCH v6 0/6] TDA1997x HDMI video receiver
by Tim Harvey 01 Feb '18

01 Feb '18

This is a v4l2 subdev driver supporting the TDA1997x HDMI video receiver. I've tested this on a Gateworks GW54xx/GW551x with an IMX6Q/IMX6DL which uses the TDA19971 with 16bits connected to the IMX6 CSI and single-lane I2S audio providing 2-channel audio. For this configuration I've tested both 16bit YUV422 and 8bit BT656 parallel video bus modes. While the driver should support the TDA1993 I do not have one for testing. Further potential development efforts include: - CEC support - HDCP support - mbus format selection support for bus widths that support multiple formats - TDA19972 support (2 inputs) Media graphs can be found at http://dev.gateworks.com/docs/linux/media History: v6: - tda1997x: fix return on regulator enablei in tda1997x_set_power() (Fabio) - tda1997x: fix colorspace handling (Hans) - bindings: added Robs's ack (Rob) - replace copyright with SPDX tag (Philippe) v5: - added v4l2_hdmi_colorimetry() patch from Hans to series - bindings: added Sakari's ack - tda1997x: uppercase string constants - tda1997x: use v4l2_hdmi_rx_coloriemtry to fill format - tda1997x: fix V4L2_CID_DV_RX_RGB_RANGE - tda1997x: fix interlaced mode format - dts: remove leading 0 from unit address - dts: add newline between property list and child node - dts: added missing audmux in GW551x dts v4: - move include/dt-bindings/media/tda1997x.h to bindings patch - clarify port node details in bindings - fix typos - fix default quant range for VGA - fix quant range handling and conv matrix - add additional standards and capabilities to timings_cap v3: - fix typo in dt bindings - added dt bindings for GW551x - use V4L2_DV_BT_FRAME_WIDTH/HEIGHT macros - fixed missing break - use only hdmi_infoframe_log for infoframe logging - simplify tda1997x_s_stream error handling - add delayed work proc to handle hotplug enable/disable - fix set_edid (disable HPD before writing, enable after) - remove enabling edid by default - initialize timings - take quant range into account in colorspace conversion - remove vendor/product tracking (we provide this in log_status via infoframes) - add v4l_controls - add more detail to log_status - calculate vhref generator timings - timing detection fixes (rounding errors, hswidth errors) - rename configure_input/configure_conv functions v2: - encorporate feedback into dt bindings - change audio dt bindings - implement dv timings enum/cap - remove deprecated g_mbus_config op - fix dv_query_timings - add EDID get/set handling - remove max-pixel-rate support - add audio codec DAI support - added media-ctl and v4l2-compliance details v1: - initial RFC Media device topology: # media-ctl -d /dev/media0 -p Media controller API version 4.13.0 Media device information ------------------------ driver imx-media model imx-media serial bus info hw revision 0x0 driver version 4.13.0 Device topology -

[alsa-devel] [PATCH v5 0/6] ASoC: Intel: Skylake: Add a clk driver to enable ssp clks early
by Sriram Periyasamy 26 Jan '18

26 Jan '18

For certain platforms, clocks (mclk/sclk/fs) are required to be up before the stream start. Example: some codecs needs the mclk/sclk/fs to be enabled early for a successful clock synchronization. Some platforms require clock to be enabled at boot and be always ON. By sending set_dma_control IPC (with the i2s blobs queried from NHLT), these clocks can be enabled early after the firmware is downloaded. With this series, a virtual clock driver is created which provides interface to send the required IPCs from machine driver to enable the clocks. NHLT is parsed during probe and the clock information is populated. The pointer to blob is cached and sent along with the set_dma_control IPC structure during the clk prepare/unprepare callback. Clocks are created for a ssp if the nhlt table has endpoint configuration for that particular ssp. Kabylake machine driver uses the clock interface to enable the clocks early as it is required by the rt5663 driver for clock synchronization. v4 -> v5 - Remove checks for clock enable status from machine driver since taken care in the framework already - Add check in the skl_clk_set_rate to avoid different rates when clock is enabled already v3 -> v4 - Add missing signed-offs v2 -> v3 - Moved the clk ops and IPCs from Skylake driver to clk driver and reordered commits accordingly - Add the support for extended I2S blob config which supports multiple mclk dividers in NHLT - Enable the clocks as well in DAPM PMU event instead of hw_params in machine drivers as confirmed by codec vendor - Do not register the clk if there is no valid clock source is avail in the I2S blob - Take care of error return in the clk driver - Address rest of the review comments and more optimization added - Fix the warning sound/soc/intel/skylake/skl.c:724:1-3: WARNING: PTR_ERR_OR_ZERO can be used reported by scripts/coccinelle/api/ptr_ret.cocci - Modified DSP replies as human readable to ease the debugging - Add firmware replies for MCLK/SCLK clocks if they are running already v1 -> v2 - Register parent clocks with skylake device. With the patch "clk: Add support for runtime PM" soon to be merged will help DSP to stay active on call to clock enable.

[alsa-devel] [PATCH] ASoC: rockchip: Use dummy_dai for rt5514 dsp dailink

[alsa-devel] [PATCH 0/2] sunxi: Add Capture support for sun8i-a33
by Mylène Josserand 25 Jan '18

25 Jan '18

Hello everyone, Here is a first series to add support for the capture for Allwinner Sun8I-A33 SoC (sun8i-codec). These patches have been tested on Sun8i-r16 parrot board and the two microphones are working well. Noticed that the DAPM route is not correct: "Right/Left Digital ADC Mixer" widgets should be after the "Right ADC" (according to what I understood from the datasheet). This is currently not the case but when I tried to update it, I got an error about "failing to add routes". I will investigate why in next weeks (and send a V2) but as it can take time, I think it is better to send a V1 and got reviews (because it is the first time I am implementing such features). Thank you in advance, Best regards, Mylène Mylène Josserand (2): ASoC: sun8i-codec: Add ADC support for a33 ARM: dts: sun8i: Add ADC routing arch/arm/boot/dts/sun8i-a33.dtsi | 10 ++++- sound/soc/sunxi/sun8i-codec.c | 82 +++++++++++++++++++++++++++++++++++++++- 2 files changed, 89 insertions(+), 3 deletions(-) -- 2.11.0

[alsa-devel] [PATCH for-4.15] ASoC: rt5514: don't assume rt5514 component was "attached"
by Brian Norris 24 Jan '18

24 Jan '18

I've found that on Google's "Kevin" Chromebook, the rt5514 codec might not be set up completely, yet its device is still present, and therefore its PM suspend/resume is called. This hits a NULL pointer exception, since we never had the chance to set our drvdata pointer. This resolves crashes seen when trying to resume my system.

19 Jan '18

From: mahendran.k <mahendran.kuppusamy(a)in.bosch.com> For long time test case, the slave_hw_ptr will exceed the boundary and wraparound the slave_hw_ptr. This slave boundary wraparound will cause the rate->hw_ptr to wraparound irrespective of the rate->boundary availability and due to that the available size goes wrong. Hence, To get the correct available size, - Its necessary to increment the rate->hw_ptr upto the rate->boundary and then wraparound the rate->hw_ptr. - While handling fraction part of slave period, rounded value will be introduced by input_frames().
