* ASoC: tegra: convert to standard DMA DT bindingsStephen Warren2013-12-111-0/+5
| | | | | | | | | | | | 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: Use common DAI DMA data structLars-Peter Clausen2013-04-031-7/+0
| | | | | | | | | | Use the common DAI DMA data struct for tegra, this allows us to use the common helper function to configure the DMA slave config based on the DAI DMA data.

* ARM: tegra: remove <mach/dma.h>Stephen Warren2012-11-051-2/+0
| | | | | | | | | | | | | | | Remove includes of <mach/dma.h> from sound/soc; nothing from it is used. Remove include of <mach/dma.h> from mach-tegra/apbio.c; since the DMA transfers made by this file don't need flow-control with any peripheral, there's no need to set any slave ID. Once those changes are made, there are no remaining users of <mach/dma.h> so remove it. Drivers should get this information from device tree. This removal is necessary for single zImage.

* ASoC: tegra: remove support of legacy DMA driver based accessLaxman Dewangan2012-09-171-14/+0
| | | | | | | | | | | Remove the support code which uses the legacy APB DMA driver for accessing the I2S FIFO. The driver will use the dmaengine based APB DMA driver for accessing reqding/writing to I2S FIFO.

* ASoC: tegra: use dmaengine based dma driverLaxman Dewangan2012-07-031-0/+2
| | | | | | | | | | | | | | | | | | | Use the dmaengine based Tegra APB DMA driver for data transfer between SPI fifo and memory in place of legacy Tegra APB DMA. Because generic soc-dmaengine-pcm uses the DMAs API based on dmaengine, using the exported APIs provided by this generic driver. The new driver is selected if legacy driver is not selected and new dma driver is enabled through config file.

* ASoC: tegra: register 'platform' from DAIs, get rid of pdevStephen Warren2012-04-011-1/+4
| | | | | | | | | | | | | | | | | Previously, the ASoC 'platform' (PCM/DMA) object was instantiated via a platform_device. This didn't represent the hardware well, since there was no separate hardware associated with this platform_device; it was a virtual device with sole purpose to call snd_soc_register_platform(). This mechanism required all board files to register this device, and all ASoC machine drivers to create and register this device when booting using device tree. This change removes the platform_device completely. Each Tegra DAI now registers the ASoC 'platform' itself. Machine drivers are adjusted for the new 'platform' name.
