[alsa-devel] [PATCH 1/1] ASoC: bcm2835-i2s: Support 384k sample rate
by Clive Messer 10 Nov '17

10 Nov '17

Add support for sample rates up to 384k to bcm2835-i2s driver, with SNDRV_PCM_RATE_CONTINUOUS and specifying 8k min and 384k max, for both playback and capture.

[alsa-devel] [PATCH 00/14] soundwire: Add a new SoundWire subsystem
by Vinod Koul 10 Nov '17

10 Nov '17

So today we celebrate Diwali, the festival of lights in this part of the world. On this occasion I would like to add a new Linux subsystem. 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_v1 This is first version of the patch which incorporates lots of changes based on the RFC series posted last year https://lkml.org/lkml/2016/10/21/395 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 (10): 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 module soundwire: intel: Add Intel Master driver soundwire: intel: Add Intel init module Documentation/soundwire/summary.txt | 192 +++++++ drivers/Kconfig | 2 + drivers/Makefile | 1 + drivers/base/regmap/Kconfig | 4 + drivers/base/regmap/Makefile | 1 + drivers/base/regmap/regmap-sdw.c | 146 +++++ drivers/soundwire/Kconfig | 37 ++ drivers/soundwire/Makefile | 18 + drivers/soundwire/bus.c | 983 ++++++++++++++++++++++++++++++++ drivers/soundwire/bus.h | 119 ++++ drivers/soundwire/bus_type.c | 245 ++++++++ drivers/soundwire/cadence_master.c | 793 ++++++++++++++++++++++++++ drivers/soundwire/cadence_master.h | 94 +++ drivers/soundwire/intel.c | 395 +++++++++++++ drivers/soundwire/intel.h | 70 +++ drivers/soundwire/intel_init.c | 230 ++++++++ drivers/soundwire/mipi_disco.c | 421 ++++++++++++++ drivers/soundwire/slave.c | 173 ++++++ drivers/soundwire/sysfs.c | 396 +++++++++++++ include/linux/mod_devicetable.h | 7 + include/linux/regmap.h | 37 ++ include/linux/soundwire/sdw.h | 564 ++++++++++++++++++ include/linux/soundwire/sdw_intel.h | 72 +++ include/linux/soundwire/sdw_registers.h | 238 ++++++++ scripts/mod/devicetable-offsets.c | 5 + scripts/mod/file2alias.c | 16 + 26 files changed, 5259 insertions(+) create mode 100644 Documentation/soundwire/summary.txt 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 -- 2.7.4

[alsa-devel] [PATCH v2 0/4] TDA1997x HDMI video receiver
by Tim Harvey 07 Nov '17

07 Nov '17

This is a v4l2 subdev driver supporting the TDA1997x HDMI video receiver. I've tested this on a Gateworks GW54xx with an IMX6Q which uses the TDA19971 with 16bits connected to the IMX6 CSI. For this configuration I've tested both 16bit YUV422 and 8bit BT656 mode. 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) History: 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 RESEND1 00/12] ALSA: vsnd: Add Xen para-virtualized frontend driver
by Oleksandr Andrushchenko 02 Nov '17

02 Nov '17

From: Oleksandr Andrushchenko <oleksandr_andrushchenko(a)epam.com> This patch series adds support for Xen [1] para-virtualized sound frontend driver. It implements the protocol from include/xen/interface/io/sndif.h 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 scenarious where unprivileged OS (e.g. Android, AGL etc) use software mixers. Both capture and playback are supported.

[alsa-devel] [Patch v6 0/7] Introduce framework for SLIMbus device drivers
by srinivas.kandagatla＠linaro.org 02 Nov '17

02 Nov '17

From: Srinivas Kandagatla <srinivas.kandagatla(a)linaro.org> It's been very long time since there was any activity on the slimbus patches, Am currently working on getting Qualcomm DSP based audio working on top of mainline. Slimbus is one of the major component for getting any analog audio on QCOM SoC's. So am taking intiative to address the review comments on the older patchset and send it. I have tested this patch on IFC6410 board with wcd9310 codec. SLIMbus (Serial Low Power Interchip Media Bus) is a specification developed by MIPI (Mobile Industry Processor Interface) alliance. SLIMbus is a 2-wire implementation, which is used to communicate with peripheral components like audio-codec. SLIMbus uses Time-Division-Multiplexing to accommodate multiple data channels, and control channel. Control channel has messages to do device-enumeration, messages to send/receive control-data to/from slimbus devices, messages for port/channel management, and messages to do bandwidth allocation. Framework is introduced to support multiple instances of the bus (1 controller per bus), and multiple slave devices per controller. SPI and I2C frameworks, and comments from last time when I submitted the patches were referred-to while working on this framework. These patchsets introduce device-management, OF helpers, and messaging APIs, controller driver for Qualcomm's slimbus controller, and clock-pause feature for entering/exiting low-power mode for SLIMbus. Framework patches to do channel, port and bandwidth management are work-in-progress and will be sent out once these initial patches are accepted. These patchsets were tested on Qualcomm Snapdragon processor board using the controller driver, and a test slave device. Changes from V5 to V6: * aligned slim_driver_register more like other buses, suggested by Arnd. * removed boardinfo and add_device apis for now, suggested by Arnd * Few namespace cleanups suggested by Masami * merged of apis in to first patch as suggested by Arnd. * slimbus clients "compatible" name space made much inline with USB and PCIE, suggested by Rob and Arnd. * Removed memory allocations to controller drivers, as suggested by Arnd. * Various bindings comments addressed as suggested by Mark and others. * Added regmap interface so that codecs can write more generic code. * Added MAINTAINER file.

[alsa-devel] [PATCH] dmaengine: imx-sdma: advertise all supported slave bus widths
by Lucas Stach 31 Oct '17

31 Oct '17

The commit [1] which changed imx-pcm-dma to derive the pcm_config from the attached dmaengine introduced a regression on the supported sample formats, as imx-sdma doesn't properly advertise all the supported slave bus widths. Fix this to restore full functionality of the imx sound subsystem.
