* ASoC: tegra: Use flat regcacheDylan Reid2014-03-191-1/+1
| | | | | | | | | | | | | | | When using an rbtree cache, there can be allocations the first time a register is accessed. This can cause an attempt to schedule while atomic in the case that the regmap is using a spinlock. This could be fixed by either initializing all the registers or using a flat cache. The register maps for tegra30_ahub and tegra30_i2s are dense and don't save much from using a tree so convert them to flat. Tegra30 changes tested on Norrin, Tegra20 changes compile.

| * ASoC: tegra: convert to standard DMA DT bindingsStephen Warren2013-12-111-5/+9
| | | | | | | | | | | | | | | | | | | | | | | | By passing no flags when calling snd_dmaengine_pcm_register() from tegra_pcm.c, we end up using dma_request_slave_channel() rather than dmaengine_pcm_compat_request_channel(), and hence rely on the standard DMA DT bindings and stashing the DMA slave ID away during channel allocation. This means there's no need to use a custom DT property to store the slave ID. So, remove all the code that parsed it.

| * ASoC: tegra: allocate AHUB FIFO during probe() not startup()Stephen Warren2013-12-111-44/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Tegra30 I2S driver currently allocates DMA FIFOs from the AHUB only when an audio stream starts playback. This is theoretically nice for resource sharing, but makes no practical difference for any configuration the drivers currently support. However, this deferral prevents conversion to the standard DMA DT bindings, since conversion requires knowledge of the specific DMA channel to be allocated, which in turn depends on which specific FIFO was allocated. For this reason, move the FIFO allocation into probe() to allow later conversion to the standard DMA DT bindings.

* | ASoC: tegra: fix uninitialized variables in set_fmtStephen Warren2013-12-091-3/+3
|/ | | | | | | | | | | | | | | | | | In tegra*_i2s_set_fmt(), in the (fmt == SND_SOC_DAIFMT_CBM_CFM) case, "val" is never assigned to, but left uninitialized. The other case does initialized it. Fix this by initializing val at the start of the function, and only ever ORing into it. Update the handling of "mask" so it works the same way for consistency. Update tegra20_spdif.c to use the same code-style for consistency, even though it doesn't happen to suffer from the same problem at present.

|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
| * ASoC: tegra: support new register layouts in Tegra124Stephen Warren2013-10-141-13/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* ASoC: tegra: fix Tegra30 I2S capture parameter setupStephen Warren2013-08-151-1/+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.
