Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2012-06-25ASoC: dwc: Bodge around continuing absence of clock API stubsMark Brown
The patches for stubbing out the generic clock API still haven't been applied so we need to either add ifdefs here or add a dependency until someone decides to actually apply them. Reported-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2012-06-25ASoC: wm8996: Move register default configuration to I2C probeMark Brown
This gets the registers set up as early as possible, mainly useful for the GPIOs to ensure that they're in the correct mode. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2012-06-25ASoC: wm8996: Inline wm8996_reset() and optimise cache-only usageMark Brown
There is only one caller and this allows us to cleanly leave the CODEC with the internal LDO powered down which is the default state we're looking for and means that we can robustly disable the register cache only when we either disable the LDO or power down the external regulators.

2012-06-25ASoC: wm8996: Move regulator notifier callbacks into I2C levelMark Brown
Now that we're using regmap the cache is available here. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2012-06-25ASoC: wm8904: Move register default setup into I2C probe()Mark Brown
Get it done as early as possible, it's neater and minimises the time the pins aren't configured as requested. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2012-06-25ASoC: wm8904: Move regulator acquisition and device identification to I2CMark Brown
It's more idiomatic to have the resource allocation at this level. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2012-06-25ASoC: wm8904: Rely entirely on the core for bias level managementMark Brown
Even though the WM8904 is able to use idle_bias_off during both probe and resume we were needlessly leaving the device in standby mode. Instead power the device down as soon as we've confirmed that we can talk to it and don't manage the bias level at all over suspend and resume, the core will take us down to our minimum power level.

2012-06-20ASoC: dmaengine-pcm: Add support for querying stream position from DMA driverLars-Peter Clausen
Currently the sound dmaengine pcm helper functions implement the pcm_pointer callback by trying to count the number of elapsed periods. This is done by advancing the stream position in the dmaengine callback by one period. Unfortunately there is no guarantee that the callback will be called for each elapsed period. It may be possible that under high system load it is only called once for multiple elapsed periods. This patch addresses the issue by implementing support for querying the current stream position directly from the dmaengine driver. Since not all dmaengine drivers support reporting the stream position yet the old period counting implementation is kept for now. Furthermore the new mechanism allows to report the stream position with a sub-period granularity, given that the dmaengine driver supports this.

2012-06-20ASoC: dmaengine-pcm: Rename and deprecate snd_dmaengine_pcm_pointerLars-Peter Clausen
Currently the sound dmaengine pcm helper functions implement the pcm_pointer callback by trying to count the number of elapsed periods. This is done by advancing the stream position in the dmaengine callback by one period. Unfortunately there is no guarantee that the callback will be called for each elapsed period. It may be possible that under high system load it is only called once for multiple elapsed periods. This patch renames the current implementation and documents its shortcomings and that it should not be used anymore in new drivers. The next patch will introduce a new snd_dmaengine_pcm_pointer which will be implemented based on querying the current stream position from the dma device.

2012-06-13ASoC: probe CODECs and platforms before DAIs and linksStephen Warren
soc_probe_dai_link() currently inter-mixes the probing of CODECs, platforms, and DAIs. This can lead to problems such as a CODEC's DAI being probed before the CODEC, if that DAI is used as the CPU-side of a DAI link without any other of the CODEC's DAIs having been used as the CODEC-side of any DAI link that was probed earlier. To solve this, split soc_probe_dai_link() into soc_probe_link_components() and soc_probe_link_dais(). The former is used to probe all CODECs and platforms used by a card first, and then the latter is used to probe all the DAIs and links later. A similar change is made to soc_remove_dai_links().

2012-06-13ASoC: factor out soc_remove_platform()Stephen Warren
This change simply factors out part of soc_remove_dai_link() into a standalone function. This makes platform and CODEC removal much more similar at the call-sites. Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2012-06-13ASoC: when removing a CPU DAI, clean up its DAPM contextStephen Warren
When a standalone CPU DAI (one not part of a CODEC) is probed, widgets are created for it. Add a call to snd_soc_dapm_free() in order to clean these up when the CPU DAI is removed. In order for snd_soc_dapm_free() to work, the CPU DAI's DAPM context's list member must be initialized, since snd_soc_dapm_free() removes that from the list it's part of. Add it to the card's list of DAPM contexts. Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2012-06-13ASoC: when initializing CPU DAI, don't duplicate any CODEC initStephen Warren
If the CPU-side of a DAI link is a CODEC rather than a standalone DAI, the codec initialization will call try_module_get() and create the DAI widgets. Ensure that this isn't duplicated when the CPU DAI itself is probed, if the CPU DAI is part of a CODEC. Note that this is not a complete fix on its own, since there's no guarantee that the CODEC itself will be initialized - currently that only happens if the CODEC is also used as the CODEC-side of a DAI link, and that initialization may happen before or after the DAIs within the CODEC are initialized. However, such a scenario doesn't necessarily currently work, and I don't think this change alone makes it any worse. This is fixed in a couple patches time.

2012-06-12ASoC: tegra+wm8903: turn of mic detect when card is removedStephen Warren
If mic detect is left enabled and the WM8903 detects a status change, the WM8903 driver will make a callback against the free()d jack, which will cause a crash.

2012-06-12ASoC: wm8903: Move interrupt request to I2C probeMark Brown
There's no reason to defer requesting of the interrupt until the CODEC probe and doing so results in more work if we hit an error as we'll have registered the CODEC with the core.
