[alsa-devel] [PATCH 0/2] ALSA: usb-audio: Insertion Control for BADD Adaptors.
by Jorge Sanjuan 14 Jun '18

14 Jun '18

This patchset adds support for the Insertion Control for BADD devices (subset of UAC3). This control is only pressent in the HEADSET ADAPTER BADD profile. The USB interrupt pipe shall be present for this profile so the status pipe creation should also happen for BADD devices. Also, the bi-directional type codes have been defined so they can be used as inferred values for the Input and Output terminals for this adapter profile. -- Based on tag: next-20180612 Jorge Sanjuan (2): ALSA: usb-audio: Add bi-directional terminal types. ALSA: usb-audio: UAC3. Add insertion control for BADD. include/uapi/linux/usb/audio.h | 8 ++++++++ sound/usb/mixer.c | 45 ++++++++++++++++++++++++++++++------------ 2 files changed, 40 insertions(+), 13 deletions(-) -- 2.11.0

[alsa-devel] [PATCH v2 0/6] soundwire: Add multi link support
by Shreyas NC 14 Jun '18

14 Jun '18

Currently, in the SoundWire subsystem, the concept of stream is limited to a Master and one or more Slaves(Codecs). This series aims to add support for multiple Master(s) sharing the same reference clock and synchronized in the hardware. This patch series adds: - Helpers to lock bus instances part of the stream - Boiler plate conversion of code to support a list of Master runtime - Support multi link bank switch to support synchronization between multiple masters - Add Intel platform ops for pre/post bank switch Changes in v2: - Add the example in Documentation as pointed out by Vinod - As Pierre suggested, added more description to the sdw_acquire_bus_lock() and sdw_release_bus_lock() API and sdw_stream_runtime data structure.

[alsa-devel] [PATCH 0/1] ALSA: usb-audio: Remove explicitly listed Mytek devices
by Jussi Laako 13 Jun '18

13 Jun '18

I missed the part that removes Mytek devices from explicit list, from the earlier patch set when merging changes from my kernel tree. This patch removes the devices already covered by the earlier patch which also covers the Mytek Liberty DAC not listed here.

[alsa-devel] [PATCH] More generic way to detect DSD capabilities
by Jussi Laako 13 Jun '18

13 Jun '18

There is a more generic way to detect DSD capability of popular UAC2 implementations. Advantage is that each new device with DSD capability doesn't have to be explicitly listed through VID:PID. XMOS/Thesycon implementation uses this method. As a safety precaution I have still left VID detection in place. Many of the implementations use XMOS' VID, but not all. I have moved over the devices that have been tested with these patches. Likely more of at least XMOS VID ones could be removed from the explicit list, but I opted for careful approach.

[alsa-devel] [PATCH v4 0/7] ASoC: add driver for Atmel I2S controller
by Codrin Ciubotariu 12 Jun '18

12 Jun '18

This is a rework of Cyrille's patches named: [PATCH v3 0/2] ASoC: add driver for Atmel I2S controller https://lkml.org/lkml/2015/9/29/454 This is the version 4 of the series, and addresses the received feedback on the mailing lists. This series applies on top of asoc-next branch of broonie/sound.git. Based on received feedback, I created a mux clock driver to select the I2S clock source, that also includes proper devicetree bindings and nodes. Also, I added the I2S nodes in sama5d2's devicetree, with the missing pin muxing for the second I2S controller. This series of patches adds support to the new Atmel I2S controller embedded on sama5d2 SoCs. ChangeLog v3 -> v4 - as suggested by Rob Herring: - added a clock mux driver for I2S's clock control bit; - more precise description of I2S's devicetree bindings; - removed SoC and internal detalls from bindings; - addressed comments from Mark Brown; - added devicetree nodes and pin muxing for I2S; v2 -> v3 - fix the coding style, add some more comments and add a section dedicated to sama5d2 SoCs in the DT binding documentation as suggested by Mark Brown. v1 -> v2 - initialize dev->dev before calling dev->caps->mck_init() Codrin Ciubotariu (3): dt-bindings: clk: at91: add an I2S mux clock clk: at91: add I2S clock mux driver ARM: dts: at91: sama5d2: add I2S clock muxing nodes Cyrille Pitchen (4): ASoC: atmel-i2s: dt-bindings: add DT bindings for I2S controller ASoC: atmel-i2s: add driver for the new Atmel I2S controller ARM: dts: at91: sama5d2: add nodes for I2S controllers ARM: dts: at91: sama5d2 Xplained: add pin muxing for I2S .../devicetree/bindings/clock/at91-clock.txt | 34 + .../devicetree/bindings/sound/atmel-i2s.txt | 47 ++ arch/arm/boot/dts/at91-sama5d2_xplained.dts | 28 + arch/arm/boot/dts/sama5d2.dtsi | 52 ++ arch/arm/mach-at91/Kconfig | 4 + drivers/clk/at91/Makefile | 1 + drivers/clk/at91/clk-i2s-mux.c | 117 ++++ sound/soc/atmel/Kconfig | 9 + sound/soc/atmel/Makefile | 2 + sound/soc/atmel/atmel-i2s.c | 765 +++++++++++++++++++++ 10 files changed, 1059 insertions(+) create mode 100644 Documentation/devicetree/bindings/sound/atmel-i2s.txt create mode 100644 drivers/clk/at91/clk-i2s-mux.c create mode 100644 sound/soc/atmel/atmel-i2s.c -- 2.7.4
