[alsa-devel] [PATCH v2] ASoC: use seq_file to dump the contents of dai_list, platform_list and codec_list
by Donglin Peng 08 Feb '18

08 Feb '18

Now the debugfs files dais/platforms/codecs have a size limit PAGE_SIZE and the user can not see the whole contents of dai_list/platform_list/codec_list when they are larger than this limit. This patch uses seq_file instead to make sure dais/platforms/codecs show the full contents of dai_list/platform_list/codec_list.

[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 v7 0/6] TDA1997x HDMI video receiver
by Tim Harvey 06 Feb '18

06 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: v7: - fix interlaced mode - support no AVI infoframe (ie DVI) (Hans) - add support for multiple output formats (Hans) 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: -

[alsa-devel] [PATCH] ASoC: codecs: Add support for AK5558 ADC driver
by Daniel Baluta 02 Feb '18

02 Feb '18

AK5558 is a 32-bit, 768 kHZ sampling, differential input ADC for digital audio systems. Datasheet is available at: https://www.akm.com/akm/en/file/datasheet/AK5558VN.pdf Initial patch includes support for normal and TDM modes.
