[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.

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 -

[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.
