[alsa-devel] ESI Juli@ crash with external clock switch - patch
by Pavel Hofman 28 Jan '15

28 Jan '15

Hi, I have investigated a crash/kernel thread lockup when Juli@ is switched to external SPDIF clock and the incoming SPDIF stream changes samplerate. The problem appears to occur in the timed thread in charge of reading incoming samplerate and acting upon its change. The problem disappears with the following patch: diff --git a/sound/i2c/other/ak4114.c b/sound/i2c/other/ak4114.c index c7f5633..68bb326 100644 --- a/sound/i2c/other/ak4114.c +++ b/sound/i2c/other/ak4114.c @@ -154,7 +154,7 @@ void snd_ak4114_reinit(struct ak4114 *chip) { chip->init = 1; mb(); - flush_delayed_work(&chip->work); + //flush_delayed_work(&chip->work); ak4114_init_regs(chip); /* bring up statistics / event queing */ chip->init = 0; I am afraid I do not know enough about kernel workqueues to determine whether this "fix" is OK. Interestingly, the almost identical driver ak4113.c for a very similar card Infrasonic Quartet (ice1724/quartet.c) does not suffer from this problem (tested now). Thanks a lot for your opinion. Best regards, Pavel Hofman.

[alsa-devel] [PATCH v2 0/7] ASoC: pcm512x: Clock master modes
by Peter Rosin 28 Jan '15

28 Jan '15

From: Peter Rosin <peda(a)axentia.se> Hi! [ Note that the dt change is in patch 5/7, for those only interested in that particular bit. ] This series implements BCLK master modes for the pcm512x driver. It has only been tested with the pcm5142 chip, but they are from the same family and should be compatible. I have mainly used the spec for the newer pcm5242 chip (also from the same family) as it fills in a lot of blanks in the pcm512x/pcm514x specs. The code has also seen most of its testing in a 3.10 environment, so there might be some forward-porting warts. But it is able to play sound in 3.18 as well, and most of the changes have little to do with anything but the clocking in the chip itself. Changes since v1: - Use snd_soc_params_to_frame_size and snd_soc_params_to_bclk instead of implementing home-grown versions based on the physical width. The I2S-communication will no longer have padding bits for S24_LE. Cheers, Peter Peter Rosin (7): ALSA: pcm: Add snd_interval_ranges() and snd_pcm_hw_constraint_ranges() ASoC: pcm512x: Fix spelling of register field names. ASoC: pcm512x: Change register default to match actual content after reset ASoC: pcm512x: Support mastering BCLK/LRCLK without using the PLL ASoC: pcm512x: Support mastering BCLK/LRCLK using the PLL ASoC: pcm512x: Avoid the PLL for the DAC clock, if possible ASoC: pcm512x: Support SND_SOC_DAIFMT_CBM_CFS .../devicetree/bindings/sound/pcm512x.txt | 25 +- include/sound/pcm.h | 12 + sound/core/pcm_lib.c | 85 ++ sound/soc/codecs/pcm512x.c | 933 +++++++++++++++++++- sound/soc/codecs/pcm512x.h | 109 ++- 5 files changed, 1139 insertions(+), 25 deletions(-) -- 1.7.10.4

[alsa-devel] [PATCH v3 00/10] Improvements to Tegra-based Chromebook support
by Tomeu Vizoso 28 Jan '15

28 Jan '15

v3: * Added bindings for the LTN140AT29 panel * Removed the delay in pwrseq, as what was actually needed was to add a dependency on the power supplies of the host * Uses the pinmux for the Blaze as generated by tegra-pinmux-scripts * Uses the pinmux for the Big as in the last patch from Simon Glass Hello, this series adds support for the Tegra-based HP Chromebook 14 (aka nyan blaze), which is very similar to the Acer Chromebook 13 (aka nyan big). Because they both include tegra124-nyan.dtsi, some improvements to Blaze support have also benefitted the Big. I have tested that USB2, the panels, HDMI, the trackpad, Wifi and sound work on both. The DT for the Big includes the pinmux configuration as generated by tegra-pinmux-scripts with Simon's patch at: https://patchwork.ozlabs.org/patch/417779/ These patches are based on top of linux-next 20150128. http://cgit.collabora.com/git/user/tomeu/linux.git/log/?h=nyan-v3 Regards, Tomeu Stéphane Marchesin (1): drm/panel: add support for Samsung LTN140AT29 panel Tomeu Vizoso (9): ARM: tegra: Set the sound card model that alsaucm expects ARM: tegra: Move out nyan-generic parts out from the nyan-big DT ARM: tegra: Add DTS for the nyan-blaze board ARM: tegra: Add node for trackpad in Nyan boards ASoC: tegra: Add a control for the headphone switch ASoC: tegra: add sink for the internal mic to tegra_max98090 ARM: tegra: Use pwrseq-simple for the wifi in Nyan ARM: tegra: Use the generated pinmux data ARM: tegra: Set spi-max-frequency property to flash node .../bindings/panel/samsung,ltn140at29-301.txt | 7 + .../bindings/sound/nvidia,tegra-audio-max98090.txt | 1 + arch/arm/boot/dts/Makefile | 1 + arch/arm/boot/dts/tegra124-nyan-big.dts | 2112 +++++++++++--------- arch/arm/boot/dts/tegra124-nyan-blaze.dts | 1325 ++++++++++++ arch/arm/boot/dts/tegra124-nyan.dtsi | 692 +++++++ drivers/gpu/drm/panel/panel-simple.c | 26 + sound/soc/tegra/tegra_max98090.c | 3 + 8 files changed, 3206 insertions(+), 961 deletions(-) create mode 100644 Documentation/devicetree/bindings/panel/samsung,ltn140at29-301.txt create mode 100644 arch/arm/boot/dts/tegra124-nyan-blaze.dts create mode 100644 arch/arm/boot/dts/tegra124-nyan.dtsi -- 1.9.3
