[alsa-devel] [PATCH] ASoC: core: don't try to resume uninstantiated a soc-audio devices
by Daniel Mack 23 Nov '11

23 Nov '11

The code tries to schedule a work item from the resume context, which will crash the kernel if snd_soc_instantiate_card() has not been called for the card before. The bug I triggered is related to 82e14e8b ("ASoC: core: Don't schedule deferred_resume_work twice"), hence a backport to 3.1 is necessary.

[alsa-devel] [PATCH v2 1/3] ASoC: Implement fully_routed card property
by Stephen Warren 23 Nov '11

23 Nov '11

A card is fully routed if the DAPM route table describes all connections on the board. When a card is fully routed, some operations can be automated by the ASoC core. The first, and currently only, such operation is described below, and implemented by this patch. Codecs often have a large number of external pins, and not all of these pins will be connected on all board designs. Some machine drivers therefore call snd_soc_dapm_nc_pin() for all the unused pins, in order to tell the ASoC core never to activate them. However, when a card is fully routed, the information needed to derive the set of unused pins is present in card->dapm_routes. In this case, have the ASoC core automatically call snd_soc_dapm_nc_pin() for each unused codec pin. This has been tested with soc/tegra/tegra_wm8903.c and soc/tegra/trimslice.c. v2: Rename flag from auto_nc_pins to fully_routed. Adjust description.

[alsa-devel] [PATCH 00/17] ASoC: Add Tegra DT, cleanup, and related
by Stephen Warren 23 Nov '11

23 Nov '11

These patches add device tree bindings for all the Tegra ASoC components, and the WM8903 codec. Also included is some general Tegra driver cleanup, and a solution for the "snd_soc_dapm_nc_pin" open-coding. The ASoC and arch/arm changes should be independent enought that they can be applied to their separate trees without issue to those trees standalone, and will meet in linux-next just fine. The arch/arm .dts/*.dts changes depend on the .dtsi/.dts cleanup patches that I posted yesterday for context. I tested this on: Harmony, Seaboard: non-DT and DT: Tested audio capture & playback. Trimslice: non-DT and DT: Tested audio playback. Capture appears to be broken before my patches. Ventana: DT: Tested audio capture & playback. Paz00: DT: Tested booting with the patches applied.

[alsa-devel] [PATCH v2] ASoC: Tegra I2S: Remove dependency on pdev->id
by Stephen Warren 23 Nov '11

23 Nov '11

When devices are instantiated from device-tree, pdev->id is set to -1. Rework the driver so it doesn't depend on the ID. Tegra I2S instantiated from board files are configured with pdev name "tegra-i2s" and ID 0 or 1. The driver core then names the device "tegra-i2s.0" or "tegra-i2s.1". This is not changing. When a device is instantiated from device-tree, it will have pdev->name="" and pdev->id=-1. For this reason, the pdev->id value is not something we can rely on. This patch doesn't actually change any names though: When a device is instantiated from device-tree, the overall device name will be "${unit_address}.${node_name}". This causes issues such as clk_get() failures due to lack of a device-name match. To solve that, AUXDATA was invented, to force a specific device name, thus allowing dev_name() to return the same as the non-device-tree case. Tegra currently uses AUXDATA for the I2S controllers. Eventually, AUXDATA will go away, most likely replaced by phandle-based references within the device tree. v2: * Use dev_name(&pdev->dev) instead of pdev->name. * Expand commit description.

Hello, The following series will add support for OMAP4 DMIC interface, and enable them on sdp4430/Blaze boards. Mark: The Panda support will be based on this series with the conversion of the sdp4430 ASoC machine driver to platform device/driver to prepare it for DT. The DT bindings for the dmic driver will be sent shortly as well.
