2015-07-07ASoC: fsl: Add dedicated DMA buffer size for each cpu daiShengjiu Wang
As the ssi is not the only cpu dai, there are esai, spdif, sai. and imx_pcm_dma can be used by all of them. Especially ESAI need a larger DMA buffer size. So Add dedicated DMA buffer for each cpu dai.

2013-07-31ASoC: fsl: Fix module buildFabio Estevam
Building imx_v6_v7_defconfig with all audio drivers as modules results in the folowing build error: ERROR: "imx_pcm_fiq_init" [sound/soc/fsl/snd-soc-imx-ssi.ko] undefined! ERROR: "imx_pcm_dma_init" [sound/soc/fsl/snd-soc-imx-ssi.ko] undefined! ERROR: "imx_pcm_fiq_exit" [sound/soc/fsl/snd-soc-imx-ssi.ko] undefined!

ERROR: "imx_pcm_dma_exit" [sound/soc/fsl/snd-soc-fsl-ssi.ko] undefined! Fix this by allowing SND_SOC_IMX_PCM_FIQ and SND_SOC_IMX_PCM_DMA to be also built as modules and by using 'IS_ENABLED' to cover the module case.

2013-07-25ASoC: fsl: Set sdma peripheral type directlyNicolin Chen
Let CPU DAI drivers set SDMA periperal type directly to support more dma types(SPDIF, ESAI) other than only two for SSI. This will easily allow some non-SSI drivers to use the imx-pcm-dma as well.

2013-05-15ASoC: fsl: remove imx-pcm driverShawn Guo
With imx-pcm-dma moving to generic dmaengine pcm driver and the removal of imx-pcm-audio/imx-fiq-pcm-audio platform device use, now imx-pcm driver contains a few functions that are only used by imx-pcm-fiq.c. Move these functions into imx-pcm-fiq.c and remove imx-pcm.c completely. Signed-off-by: Shawn Guo <shawn.guo@linaro.org> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

2013-04-05ASoC: fsl: Use common DAI DMA data structLars-Peter Clausen
Use the common DAI DMA data struct for fsl/imx, this allows us to use the common helper function to configure the DMA slave config based on the DAI DMA data.

2013-03-26ASoC: imx-pcm: Embed the imx_dma_data struct in the dma_params structLars-Peter Clausen
Currently the imx_dma_data struct, which gets passed to the dmaengine driver, is allocated and constructed in the pcm driver from the data stored in the dma_params struct. The dma_params struct gets passed to the pcm driver from the dai driver. Instead of going this route of indirection embed the dma_data struct directly into the dma_params struct and let the dai driver fill it in. This allows us to simplify the imx-pcm-dma driver quite a bit, since it doesn't have care about memory managing the imx_dma_data struct anymore.

2013-01-28ASoC: fsl: fix snd-soc-imx-pcm module buildShawn Guo
When building modules with CONFIG_SND_IMX_SOC=m in imx_v6_v7_defconfig, we will see the following link error. LD [M] sound/soc/fsl/snd-soc-fsl-ssi.o LD [M] sound/soc/fsl/snd-soc-fsl-utils.o LD [M] sound/soc/fsl/snd-soc-imx-ssi.o LD [M] sound/soc/fsl/snd-soc-imx-audmux.o LD [M] sound/soc/fsl/snd-soc-imx-pcm.o sound/soc/fsl/imx-pcm-dma.o: In function `init_module': imx-pcm-dma.c:(.init.text+0x0): multiple definition of `init_module' sound/soc/fsl/imx-pcm-fiq.o:imx-pcm-fiq.c:(.init.text+0x0): first defined here sound/soc/fsl/imx-pcm-dma.o: In function `cleanup_module': imx-pcm-dma.c:(.exit.text+0x0): multiple definition of `cleanup_module' sound/soc/fsl/imx-pcm-fiq.o:imx-pcm-fiq.c:(.exit.text+0x0): first defined here make[4]: *** [sound/soc/fsl/snd-soc-imx-pcm.o] Error 1 The module snd-soc-imx-pcm is designed to link imx-pcm.o with imx-pcm-dma.o or imx-pcm-fiq.o depending on if option SND_SOC_IMX_PCM_DMA or SND_SOC_IMX_PCM_FIQ is enabled. Both imx-pcm-dma and imx-pcm-fiq register their own module_platform_driver. However, these two options are not mutually exclusive and can be enabled together. And that's why we see above multiple init_module definition error. Instead of having both imx-pcm-dma and imx-pcm-fiq register their own platform_driver, we should do only once in imx-pcm.c. Using platform_device_id to distinguish between imx-pcm-dma and imx-pcm-fiq, we can run-time call imx-pcm-dma/fiq specific initialization in .probe hook to have module snd-soc-imx-pcm work for both cases.

2012-04-01ASoC: imx: merge sound/soc/imx into sound/soc/fslShawn Guo
Freescale PowerPC and ARM/IMX families share the same SSI IP block. The patch merges sound/soc/imx into sound/soc/fsl, so that the possible code sharing and consolidation can happen. This is a plain merge, except that menuconfig SND_POWERPC_SOC is added in Kconfig for PowerPC platform as a correspondence to SND_IMX_SOC for IMX platform.
