[alsa-devel] [PATCH] ALSA: hda - Fix mute LED on HP laptops in runtime suspend
by Takashi Iwai 24 Oct '13

24 Oct '13

When HP laptops with mute and mic-record LEDs go to runtime suspend, these LEDs are turned on forcibly no matter whether GPIO pis are on or off. This strange behavior seems triggered by resetting the HD-audio bus link at azx_rutime_suspend(). So, just add a new hda_bus flag to avoid the link reset at runtime suspend and set it for these HP machines.

[alsa-devel] [PATCH] ALSA: hda - Fix unbalanced runtime PM refcount after S3/S4
by Takashi Iwai 24 Oct '13

24 Oct '13

When a machine goes to S3/S4 after power-save is enabled, the runtime PM refcount might be incorrectly decreased because the power-down triggered soon after resume assumes that the controller was already powered up, and issues the pm_notify down. This patch fixes the incorrect pm_notify call simply by checking the current value properly.

[alsa-devel] [PATCH v2 00/11] Fix AM335x-evm analog audio support
by jsarha＠ti.com 23 Oct '13

23 Oct '13

From: Jyri Sarha <jsarha(a)ti.com> The first version of patches can been found here: http://mailman.alsa-project.org/pipermail/alsa-devel/2013-September/066178.… Changes for v2 - Dropped our "ASoC: davinci-mcasp: Add pinctrl support" since driver core is taking care of this now. - Cleanup am33xx audio build - Add regulators to tlv320aic3x DT binding document - Remove dm365-voice-codec-audio DT support as it has never been tested an probably does not work - Add output pins and Line In connector to davinci-evm-audio DT binding doc - Remove asp_chan_q and ram_chan_q properties from mcasp DT node in DT mode mcasp is hardcoded to event queue 0 (highest priority) - Add pins to tlv320aic3x DT bindings document. If I misunderstood Marks comment and this patch is not needed, then just leave it out Changes based on TI internal discussions - Move system clock rate logic away from from evm_hw_params soc-op - Remove unnecesary #if defined(CONFIG_OF) from davinci-evm.c - Make dma property DT binding document more exact - Add only "dma" reg location instead of separate "dma-tx" and "dma-rx" - Primarily look for "mpu" reg property, but fall back to index 0 if not found - Remove interrupt property from mcasp DT node as it is not used - Remove #address-cells and #size-cells mcasp properties as they are not needed This set of patches fixes the basic audio support for am335x-evm. It should also be relatively simple to add the necessary nodes to relevant dts files to get BeagleBone + AudioCape and am335x-evmsk working too. The patch set depends on following patches: [PATCH v11 4/8] ARM: dts: add AM33XX EDMA support https://lkml.org/lkml/2013/6/18/49 [PATCH v11 5/8] ARM: dts: add AM33XX SPI DMA support https://lkml.org/lkml/2013/6/18/55 [PATCH v2] ARM: EDMA: Fix clearing of unused list for DT DMA resources https://lkml.org/lkml/2013/7/22/441 I have tried my best not to break the existing support for older davinci boards, but since I do not have those boards I can not be sure. Some commit comments refer to a dmaengine based davinci audio implementation which is planned for but nothing has been done yet. Best regards, Jyri Darren Etheridge (1): ARM/dts: am335x-evm: Add audio support for am335x-evm.dts Hebbar, Gururaja (2): ASoC: davinci-evm: Add device tree binding ASoC: davinci: Add support for AM33xx SoC Audio Jyri Sarha (7): ASoC: davinci-evm: Move sysclk logic away from evm_hw_params ASoC: davinci-mcasp: Add DMA register locations to DT ASoC: davinci-mcasp: Extract DMA channels directly from DT ASoC: davinci-mcasp: Remove interrupt property from DT bindings doc ASoC: tlv320aic3x: Add regulators to DT bindings document ASoC: tlv320aic3x: Add codec pins to DT bindings document ARM/dts: am33xx: mcasp: Add new dma register location to reg-property Pantelis Antoniou (1): ARM/dts: am33xx: Add mcasp0 and mcasp1 device tree entries .../bindings/sound/davinci-evm-audio.txt | 58 ++++++ .../bindings/sound/davinci-mcasp-audio.txt | 15 +- .../devicetree/bindings/sound/tlv320aic3x.txt | 26 +++ arch/arm/boot/dts/am335x-evm.dts | 56 ++++++ arch/arm/boot/dts/am33xx.dtsi | 25 +++ include/linux/platform_data/davinci_asp.h | 2 + sound/soc/davinci/Kconfig | 18 +- sound/soc/davinci/Makefile | 1 + sound/soc/davinci/davinci-evm.c | 184 +++++++++++++++++--- sound/soc/davinci/davinci-mcasp.c | 106 +++++++---- 10 files changed, 428 insertions(+), 63 deletions(-) create mode 100644 Documentation/devicetree/bindings/sound/davinci-evm-audio.txt -- 1.7.9.5

[alsa-devel] [PATCH 1/3] ASoC: samsung: Provide helper for DMA init
by Mark Brown 23 Oct '13

23 Oct '13

From: Mark Brown <broonie(a)linaro.org> In preparation for using the dmaengine helpers in ASoC rather than the dmaengine wrappers for the Samsung API wrap the configuration of dma_data. The dmaengine code expects different data to that used by the legacy API.
