[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

[alsa-devel] [PATCH] ALSA: hda/realtek - Add shutup hint
by Takashi Iwai 12 Jun '18

12 Jun '18

The pin shutup callback seems working well on some devices while it does harm on some other devices; e.g. Lenovo laptops show often the noises at (runtime) PM with the pin shutup enabled. Currently, the only way to disable the pin shutup is to hard-code spec->shutup = alc_no_shutup; in the fixup, and this makes the debugging harder for normal users. For allowing users to test the similar effect without recompiling the kernel, this patch adds a new hint string "shutup". It's a boolean value, and by passing false to this, user can turn off the pin shutup call. For example, to turn off the shutup on Lenovo P50, create a "firmware patch" file (e.g. /lib/firmware/alsa/lenovo-p50) containing the following lines: [codec] 0x10ec0298 0x17aa222e 0 [hint] shutup = no and pass the file via patch option of snd-hda-intel module (e.g. patch=alsa/lenovo-p50).

[alsa-devel] handling voice calls in ALSA soc (on Droid 4)

[alsa-devel] [PATCH] pcm: dmix: Fix hwptr updates at status call
by Takashi Iwai 12 Jun '18

12 Jun '18

In the commit 38a2d2eda880 ("pcm: dmix: Do not discard slave reported delay in status result"), the PCM dmix hwptr update code was rewritten to follow the slave PCM hwptr update. This is based on the similar change in PCM dshare, the commit faf53c197cab. There was a bug in the commit 38a2d2eda880 regarding the PCM state change, and it was addressed in commit 3752e6b8733d ("pcm: dmix: Fix the inconsistent PCM state"). However, we've hit yet another bug in this commit. Namely, the hwptr update was forgotten in the snd_pcm_dmix_sync_ptr0() function. So the hwptr value passed from snd_pcm_dmix_status() isn't properly stored, and it screws up at some long run occasionally. This patch covers the bug by replacing with the right value.

Unfortunately, other devices (e.g. Philips Wecall) with the very same ID got broken by this change, spewing an error like: usb 2-1.8.2: 2:1: cannot set freq 48000 to ep 0x3 Until we find a proper solution, fix the regression at first by disabling the added quirk entry.
