2015-07-07ASoC: fsl: Add dedicated DMA buffer size for each cpu daiShengjiu Wang1-2/+7
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 Estevam1-2/+2
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 Chen1-5/+2
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 Guo1-5/+0
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 Clausen1-11/+5
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 Clausen1-2/+15
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 Guo1-0/+18
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 Guo1-0/+32
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.
