2013-10-25Merge tag 'asoc-v3.13' of ↵Takashi Iwai7-29/+186
git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-next ASoC: Updates for v3.13 - Further work on the dmaengine helpers, including support for configuring the parameters for DMA by reading the capabilities of the DMA controller which removes some guesswork and magic numbers fromm drivers. - A refresh of the documentation. - Conversions of many drivers to direct regmap API usage in order to allow the ASoC level register I/O code to be removed, this will hopefully be completed by v3.14. - Support for using async register I/O in DAPM, reducing the time taken to implement power transitions on systems that support it.

2013-10-14ASoC: tegra: support new register layouts in Tegra124Stephen Warren6-28/+186
Tegra124 introduces some small changes to the layout of some registers. Modify the affected drivers to program those registers appropriately based on which SoC they're running on. Tegra124 also introduced some new modules on the AHUB configlink register bus. These will require new entries in configlink_clocks[] in the AHUB driver. However, supporting that change likely relies on switching Tegra to the common reset framework, so I'll defer that change for now.

Remove unneeded error handling on the result of a call to platform_get_resource when the value is passed to devm_ioremap_resource.

Add a Mic Jack widget to the Tegra+RT5640 machine driver, and document this in the DT binding. This enables the DT to include the Mic Jack in the audio routing table, and hence enables capture of audio, in addition to the previously-working playback.

2013-08-15ASoC: tegra: fix Tegra30 I2S capture parameter setupStephen Warren1-1/+1
The Tegra30 I2S driver was writing the AHUB interface parameters to the playback path register rather than the capture path register. This caused the capture parameters not to be configured at all, so if capturing using non-HW-default parameters (e.g. 16-bit stereo rather than 8-bit mono) the audio would be corrupted. With this fixed, audio capture from an analog microphone works correctly on the Cardhu board.

2013-06-27ASoC: ac97: Support multi-platform AC'97Mark Brown1-2/+10
Currently we can only have a single platform built in with AC'97 support due to the use of a global variable to provide the bus operations. Fix this by making that variable a pointer and having the bus drivers set the operations prior to registering. This is not a particularly good or nice approach but it avoids blocking multiplatform and a real fix involves fixing the fairly deep problems with AC'97 support - we should be converting it to a real bus.

2013-04-17ASoC: dmaengine-pcm: Make requesting the DMA channel at PCM open optionalLars-Peter Clausen1-2/+2
Refactor the dmaengine PCM library to allow the DMA channel to be requested before opening a PCM substream. snd_dmaengine_pcm_open() now expects a DMA channel instead of a filter function and filter parameter as its parameters. snd_dmaengine_pcm_close() is updated to not release the DMA channel. This allows a dmaengine based PCM driver to request its channels before the substream is opened. The patch also introduces two new functions, snd_dmaengine_pcm_open_request_chan() and snd_dmaengine_pcm_close_release_chan(), which have the same signature and behaviour of the old snd_dmaengine_pcm_{open,close}() and internally use the new variants of these functions. All users of snd_dmaengine_pcm_{open,close}() are updated to use snd_dmaengine_pcm_open_request_chan() and snd_dmaengine_pcm_close_release_chan().

The tegra dmaengine driver does not support pausing and resuming a DMA stream. The tegra PCM driver still claims to support pause and resume though and implements them by stopping and restarting the stream. This is not what an application using pause/resume would expect. Usually applications have support for working around PCMs which do not support suspend and resume, so don't set the SNDRV_PCM_INFO_PAUSE and SNDRV_PCM_INFO_RESUME flags for the tegra PCM and use the default snd_dmaengine_pcm_trigger callback.

Tegra114 requires different PLL rates. Modify the code to know about this. On Tegra114 only for now, use regular clk_get() rather than clk_get_sys() to retrieve clocks. This assumes that the clocks will be represented in device tree. We can assure that from the start of any Tegra114 audio support.

Tegra114's AHUB shares a design with Tegra30, with the followin changes: * Supports more (10 vs. 4) bi-directional FIFO channels into RAM. * Requires a separate block of registers to support the above. * Supports more attached clients, i.e. new audio multiplexing and de-multiplexing modules. * Is affected by more clocks due to the above.

Tegra only supports, and always enables, device tree. Remove all runtime checks for DT support from the driver. This allows removal of the hard-coded Harmony ASoC mapping table, since Harmony only boots with DT now. All board-specific configuration now comes from device tree, so there is no need to have a platform_data structure. Rework the driver to parse the device tree directly into struct tegra_wm8903. Also some slight re-ordering of probe() so that the code more closely resembles other drivers for easier comparison. Inparticular, the GPIO DT parsing and initial programming are moved together for each GPIO.
