[alsa-devel] [PATCH 0/3] ASoC: remove symmetric_xxx from snd_soc_dai
by Kuninori Morimoto 27 Dec '17

Hi Mark These are not important, but cleanup. Current snd_soc_dai has symmetric_xxx, but these are moved to snd_soc_dai_driver now. wm2200 is the only user now. Kuninori Morimoto (3): ASoC: wm2200: use snd_soc_codec_get_drvdata() ASoC: wm2200: don't use snd_soc_dai::symmetric_rates ASoC: soc-dai.h: remove symmetric_xxx from snd_soc_dai include/sound/soc-dai.h | 3 --- sound/soc/codecs/wm2200.c | 9 ++++++--- 2 files changed, 6 insertions(+), 6 deletions(-) -- 1.9.1

[alsa-devel] [PATCH] ALSA: hda - Clean up ALC299 init code
by Takashi Iwai 27 Dec '17

27 Dec '17

ALC299 is compatible with ALC225/295, thus it doesn't have to assign its own model. Merge together with ALC225/295 code.

[alsa-devel] [PATCH] ALSA: hda - Fix missing COEF init for ALC225/295/299
by Takashi Iwai 27 Dec '17

27 Dec '17

There was a long-standing problem on HP Spectre X360 with Kabylake where it lacks of the front speaker output in some situations. Also there are other products showing the similar behavior. The culprit seems to be the missing COEF setup on ALC codecs, ALC225/295/299, which are all compatible. This patch adds the proper COEF setup (to initialize idx 0x67 / bits 0x3000) for addressing the issue.

[alsa-devel] [PATCH v5 0/6] TDA1997x HDMI video receiver
by Tim Harvey 26 Dec '17

26 Dec '17

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. 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: v5: - added v4l2_hdmi_colorimetry() patch from Hans to series - bindings: added Sakari's ack to bindings - 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] ASoC: rt5645: Set card long_name for GPD win / pocket
by Hans de Goede 24 Dec '17

24 Dec '17

The GPD win and pocket devices both use the same codec setup and both have too generic dmi strings making snd_soc_set_dmi_name() not work. As these devices have only a single speaker we want a separate ucm file for them, which requires a unique long_name, use the existing GPD quirk handling to also provide a unique long_name.

[alsa-devel] [PATCH v3 01/27] ASOC: replace devm_ioremap_nocache with devm_ioremap
by Yisheng Xie 23 Dec '17

23 Dec '17

Default ioremap is ioremap_nocache, so devm_ioremap has the same function with devm_ioremap_nocache, which can just be killed to save the size of devres.o This patch is to use use devm_ioremap instead of devm_ioremap_nocache, which should not have any function change but prepare for killing devm_ioremap_nocache.

[alsa-devel] [RFC v1] ALSA: xen-front: Add Xen para-virtualized frontend driver
by Oleksandr Andrushchenko 22 Dec '17

22 Dec '17

Hi, all! Foreword ======== This RFC is aimed to introduce support of para-virtualized sound frontend driver for Xen [1] and gather opinions from the relevant communities (ALSA, Xen). It implements the protocol from [2] with the following limitations: - mute/unmute is not supported - get/set volume is not supported Volume control is not supported for the reason that most of the use-cases (at the moment) are based on scenarios where unprivileged OS (e.g. Android, AGL etc) uses software mixers. Both capture and playback are supported. The relevant backend is implemented as a user-space application [3] and uses accompanying helper library [4]. Both frontend driver and backend were tested on real HW running Xen hypervisor (Renesas R-Car ARM based H3/M3 boards, x86). Discussion ========== During the first attempt to upstream the driver [5] number of comments and concerns were raised, one of the biggest flaws in the design were questioned by both Clemens Ladisch [6] and Takashi Sakamoto [7]: the absence of synchronization between frontend and backend during capture/playback. Two options were discussed: “In design of ALSA PCM core, drivers are expected to synchronize to actual hardwares for semi-realtime data transmission. The synchronization is done by two points: 1) Interrupts to respond events from actual hardwares. 2) Positions of actual data transmission in any serial sound interfaces of actual hardwares. “ and finally a change to the existing protocol was suggested: “In 'include/xen/interface/io/sndif.h', there's no functionalities I described the above: 1. notifications from DomU to Dom0 about the size of period for interrupts from actual hardwares. Or no way from Dom0 to DomU about the configured size of the period. 2. notifications of the interrupts from actual hardwares to DomU.” This is implemented as a change to the sndif protocol [8] and allows removing period emulation: 1. Introduced a new event channel from back to front 2. New event with number of bytes played/captured (XENSND_EVT_CUR_POS, to be used for sending snd_pcm_period_elapsed at frontend (in Linux implementation). Sent in bytes, not frames to make the protocol generic and consistent) 3. New request for playback/capture control (XENSND_OP_TRIGGER) with start/pause/stop/resume sub-ops. Along with these changes other comments on the driver were addressed, e.g. split into smaller chunks, moved the driver from misc to xen etc. Hope, this helps to get the full picture of what was discussed and makes it possible to move forward. Waiting for your valuable comments, Thank you, Oleksandr [1] https://github.com/andr2000/linux/commits/snd_upstream_v1 [2] https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/inc… [3] https://github.com/xen-troops/snd_be [4] https://github.com/xen-troops/libxenbe [5] https://lkml.org/lkml/2017/8/7/363 [6] http://mailman.alsa-project.org/pipermail/alsa-devel/2017-August/123617.html [7] http://mailman.alsa-project.org/pipermail/alsa-devel/2017-August/123744.html [8] https://github.com/andr2000/linux/commit/095d7feae00bf00c852c67c4f1044de560…

[alsa-devel] [PATCH v5 00/15] soundwire: Add a new SoundWire subsystem
by Vinod Koul 22 Dec '17

22 Dec '17

This patch series adds a new SoundWire subsystem which implements a new MIPI bus protocol 'SoundWire'. The SoundWire protocol is a robust, scalable, low complexity, low power, low latency, two-pin (clock and data) multi-drop bus that allows for the transfer of multiple audio streams and embedded control/commands. SoundWire provides synchronization capabilities and supports both PCM and PDM, multichannel data, isochronous and asynchronous modes. This series adds SoundWire Bus, IO transfers, DisCo (Discovery and Configuration) sysfs interface, regmap and Documentation summary This patch series is also available on git://git.kernel.org/pub/scm/linux/kernel/git/vkoul/soundwire.git topic/patch_v5 v4: https://lkml.org/lkml/2017/12/1/205 v3: https://lkml.org/lkml/2017/11/30/160 v2: https://lkml.org/lkml/2017/11/10/216 v1: https://lkml.org/lkml/2017/10/18/1030 RFC: https://lkml.org/lkml/2016/10/21/395 Changes in v5: - Address comments by Pierre - add reference to mid.mipi.org in documentation - add group and master device number and don't use those for enumeration - fix unused calls in disco code and also remove superfluous initialization - remove sdw_transfer apis slave arg, make enum values integer and not bitmaps - clarify the sdw_program_device_num loop and fix interrupt handling Changes in v4: - Remove text licenses and add SPDX tags only with C99 style comments - make bus_type code as GPL v2.0 only Changes in v3: - Update the kernel-doc styles and fix included headers for files - handle dev_pm_domain_attach() for defered probe - remove OF placeholders - change regmap license to GPLv2 only Changes in v2: - move documentation into driver-api and do rst conversion - fix documentation comments - add SPDX-License-Identifier: (GPL-2.0 OR BSD-3-Clause) to all source files - rework the transfer logic and paging logic as commented on v1 - remove dummy sysfs fns - registration checks and fixes - remove slave check for regamp as that turned superfluous - remove depends SoundWire symbol - make modalias api arg const - use bitmap for tracking assigned - add counter for report present tracking todo: add the dt-bindings Sanyog Kale (4): Documentation: Add SoundWire summary soundwire: Add SoundWire MIPI defined registers soundwire: Add Slave status handling helpers soundwire: cdns: Add sdw_master_ops and IO transfer support Vinod Koul (11): soundwire: Add SoundWire bus type soundwire: Add Master registration soundwire: Add MIPI DisCo property helpers soundwire: Add IO transfer regmap: Add SoundWire bus support soundwire: Add slave status handling soundwire: Add sysfs for SoundWire DisCo properties soundwire: cdns: Add cadence library soundwire: intel: Add Intel Master driver soundwire: intel: Add Intel init module MAINTAINERS: Add SoundWire entry Documentation/driver-api/index.rst | 1 + Documentation/driver-api/soundwire/index.rst | 15 + Documentation/driver-api/soundwire/summary.rst | 207 ++++++ MAINTAINERS | 10 + drivers/Kconfig | 2 + drivers/Makefile | 1 + drivers/base/regmap/Kconfig | 4 + drivers/base/regmap/Makefile | 1 + drivers/base/regmap/regmap-sdw.c | 92 +++ drivers/soundwire/Kconfig | 37 + drivers/soundwire/Makefile | 18 + drivers/soundwire/bus.c | 967 +++++++++++++++++++++++++ drivers/soundwire/bus.h | 73 ++ drivers/soundwire/bus_type.c | 193 +++++ drivers/soundwire/cadence_master.c | 749 +++++++++++++++++++ drivers/soundwire/cadence_master.h | 48 ++ drivers/soundwire/intel.c | 347 +++++++++ drivers/soundwire/intel.h | 23 + drivers/soundwire/intel_init.c | 198 +++++ drivers/soundwire/mipi_disco.c | 370 ++++++++++ drivers/soundwire/slave.c | 115 +++ drivers/soundwire/sysfs.c | 343 +++++++++ include/linux/mod_devicetable.h | 6 + include/linux/regmap.h | 37 + include/linux/soundwire/sdw.h | 495 +++++++++++++ include/linux/soundwire/sdw_intel.h | 24 + include/linux/soundwire/sdw_registers.h | 194 +++++ include/linux/soundwire/sdw_type.h | 19 + scripts/mod/devicetable-offsets.c | 4 + scripts/mod/file2alias.c | 15 + 30 files changed, 4608 insertions(+) create mode 100644 Documentation/driver-api/soundwire/index.rst create mode 100644 Documentation/driver-api/soundwire/summary.rst create mode 100644 drivers/base/regmap/regmap-sdw.c create mode 100644 drivers/soundwire/Kconfig create mode 100644 drivers/soundwire/Makefile create mode 100644 drivers/soundwire/bus.c create mode 100644 drivers/soundwire/bus.h create mode 100644 drivers/soundwire/bus_type.c create mode 100644 drivers/soundwire/cadence_master.c create mode 100644 drivers/soundwire/cadence_master.h create mode 100644 drivers/soundwire/intel.c create mode 100644 drivers/soundwire/intel.h create mode 100644 drivers/soundwire/intel_init.c create mode 100644 drivers/soundwire/mipi_disco.c create mode 100644 drivers/soundwire/slave.c create mode 100644 drivers/soundwire/sysfs.c create mode 100644 include/linux/soundwire/sdw.h create mode 100644 include/linux/soundwire/sdw_intel.h create mode 100644 include/linux/soundwire/sdw_registers.h create mode 100644 include/linux/soundwire/sdw_type.h -- 2.7.4
