[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] [PATCH v8 0/7] TDA1997x HDMI video reciver
by Tim Harvey 08 Feb '18

08 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 - TDA19972 support (2 inputs) Media graphs can be found at http://dev.gateworks.com/docs/linux/media History: v8: - support full range of input modes based on timings_cap - add patch to fix clearing pad for VIDIOC_DV_TIMIGINGS - fix available formats for tda19971 bt656 bus width >12 - fix set_format (compliance) - fixed get/set edid (compliance) - add init_cfg to setup default pad config (compliance) - added missing pad checks to get_dv_timings_cap/enum_dv_timings (compliance) - fix alignment of if statement and whitespace in comment (Hans) - move regs to tda1997x_regs.h to clean up (Hans) - add define and sanity check for num of mbus_codes (Hans) 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] [GIT PULL] Extra ASoC updates for v4.16
by Mark Brown 07 Feb '18

07 Feb '18

This pull request is for things that arrived in the last week of the v4.15 cycle, I'm sending it directly since Takashi still seems to be on holiday (I'd thought he'd be back this week). There's some random new development in here and also a bunch of bugfixes. The I/O fix mentioned in the tag below is pretty important and would be especially good to have fixed in -rc1, it was reported right at the end of the v4.15 cycle so didn't make Takashi's early pull request and causes a power regression on some of the OMAP platforms. If this request is a problem I can do a smaller one with just that in it. Unfortunately I can't figure out how to generate a sensible git pull request for this since it ended up containing both v4.15-rc9 and my prior pull requests. When I use your tree as the reference git pull goes with your -rc9 tag so the diffstat contains way more stuff than you'll actually get but that seems to be the best alternative. The following changes since commit 0c5b9b5d9adbad4b60491f9ba0d2af38904bb4b9: Linux 4.15-rc9 (2018-01-21 13:51:26 -0800) are available in the Git repository at: https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git tags/asoc-v4.16-4 for you to fetch changes up to e0a663f24d532c7ad9ff34cc1aa96bf94c75ef44: Merge remote-tracking branch 'asoc/topic/wm8998' into asoc-next (2018-01-26 15:27:56 +0000) ---------------------------------------------------------------- ASoC: Updates for v4.16 With the merge window having been delayed for another week here's another batch of updates that came in during that week. There's a few important fixes in here, mainly a fix for I/O on a number of devices caused by some of the component rework and a fix for a potential issue if more than one component in a link provides compressed operations. ---------------------------------------------------------------- Charles Keepax (3): ASoC: compress: Correct handling of copy callback ASoC: compress: Remove some extraneous

[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.

You're correct. I don't know what happened to me when coding this, but you can safely remove this useless select statement. Cheers. -- Robert

[alsa-devel] [RESEND PATCH v2 0/9] add UniPhier audio system support
by Katsuhiro Suzuki 07 Feb '18

07 Feb '18

Hello Mark, This is the resend of patchset passed 3 weeks. https://lkml.org/lkml/2018/1/19/122 This series adds support for Socionext audio system for UniPhier LD11/LD20 SoCs. This driver supports I2S output for Line-In, Line-Out and S/PDIF output. UniPhier AIO DAI driver provides sound devices such as I2S, S/PDIF. Since the AIO has mixed register map for those I/Os, it is hard to split register areas for each sound devices. --- Changes in v2: - Add comments to aiodma_irq() - Add members to struct uniphier_aio_sub and add methods for compress audio - Expose clocking to userspace - Fix bad name 'srcport' to 'src' - Split DMA, DAI patches from large one - Validate parameters in hw_params() - Add error checks - Fix typo in error messages - Change license comment style to C++ from C Katsuhiro Suzuki (9): ASoC: uniphier: add DT bindings documentation for UniPhier AIO ASoC: uniphier: add support for UniPhier AIO common driver ASoC: uniphier: add support for UniPhier AIO DMA driver ASoC: uniphier: add support for UniPhier AIO CPU DAI driver ASoC: uniphier: add support for UniPhier AIO compress audio ASoC: uniphier: add support for UniPhier LD11/LD20 AIO driver arm64: dts: uniphier: add sound node for UniPhier arm64: dts: uniphier: add speaker out for UniPhier LD11/LD20 boards arm64: dts: uniphier: add compress audio out for UniPhier LD11/LD20 .../devicetree/bindings/sound/uniphier,aio.txt | 36 + .../boot/dts/socionext/uniphier-ld11-global.dts | 120 +++ arch/arm64/boot/dts/socionext/uniphier-ld11.dtsi | 31 + .../boot/dts/socionext/uniphier-ld20-global.dts | 120 +++ arch/arm64/boot/dts/socionext/uniphier-ld20.dtsi | 35 + sound/soc/uniphier/Kconfig | 22 + sound/soc/uniphier/Makefile | 6 + sound/soc/uniphier/aio-compress.c | 440 ++++++++ sound/soc/uniphier/aio-core.c | 1104 ++++++++++++++++++++ sound/soc/uniphier/aio-cpu.c | 570 ++++++++++ sound/soc/uniphier/aio-dma.c | 318 ++++++ sound/soc/uniphier/aio-ld11.c | 431 ++++++++ sound/soc/uniphier/aio-reg.h | 462 ++++++++ sound/soc/uniphier/aio.h | 355 +++++++ 14 files changed, 4050 insertions(+) create mode 100644 Documentation/devicetree/bindings/sound/uniphier,aio.txt create mode 100644 sound/soc/uniphier/aio-compress.c create mode 100644 sound/soc/uniphier/aio-core.c create mode 100644 sound/soc/uniphier/aio-cpu.c create mode 100644 sound/soc/uniphier/aio-dma.c create mode 100644 sound/soc/uniphier/aio-ld11.c create mode 100644 sound/soc/uniphier/aio-reg.h create mode 100644 sound/soc/uniphier/aio.h -- 2.15.0

[alsa-devel] Add Thinkpad dock support for ALC298
by Kailang 07 Feb '18

07 Feb '18

Hi Takashi, ThinkPad for ALC298 platform need to support dock device. This patch will enable it. But It need to use SSID for the quirk table. Because IdeaPad also has ALC298 platform. Use verb for the quirk table will confuse it. BR, Kailang
