Update the TI OMAP platform and machines to new multi-component model.

This patch changes the machine drivers for multi-component as follows :-

o Removed socdev o Each DAI link entry now contains platform and codec fields. o DAI link init() now passed snd_soc_pcm_runtime instread of snd_soc_codec.

This patch also changes the DAI and platform DAM drivers as follows :-

o Each platform DAI and platform DMA driver is a kernel device and can have platform data. o DAI and Platform DMA drivers have private data accessors.

Other notable changes required for multi-component support:-

o Moved zoom2 audio platform data to board-zoom2.c o Moved n810 audio platform data to board-n810.c o Moved RX51 audio platform data to board-rx51-peripherals.c o Added ASoC DAI and DMA platform devices. o Misc fixes from Jarkko Nikula

Update the TI DaVinci platform and machines to new multi-component model.

This patch changes the machine drivers for multi-component as follows :-

o Removed socdev o Each DAI link entry now contains platform and codec fields. o DAI link init() now passed snd_soc_pcm_runtime instread of snd_soc_codec.

This patch also changes the DAI and platform DAM drivers as follows :-

o Each platform DAI and platform DMA driver is a kernel device and can have platform data. o DAI and Platform DMA drivers have private data accessors.

Other notable changes required for multi-component support:-

o Added ASoC DMA platform device. o EVM now has 2 DAI links instead of #ifdef around CODEC choice. o aic3x_setup data is now platform data.

Update the Freescale i.MX platform and machines to new multi-component model.

This patch changes the machine drivers for multi-component as follows :-

o Removed socdev o Each DAI link entry now contains platform and codec fields. o DAI link init() now passed snd_soc_pcm_runtime instread of snd_soc_codec.

This patch also changes the DAI and platform DAM drivers as follows :-

o Each platform DAI and platform DMA driver is a kernel device and can have platform data. o DAI and Platform DMA drivers have private data accessors.

Other notable changes required for multi-component support:-

o Decoupled platform DMA, DAI and FIQ drivers.

Update the Renasas SuperH platform and machines to new multi-component model.

This patch changes the machine drivers for multi-component as follows :-

o Removed socdev o Each DAI link entry now contains platform and codec fields. o DAI link init() now passed snd_soc_pcm_runtime instread of snd_soc_codec.

This patch also changes the DAI and platform DAM drivers as follows :-

o Each platform DAI and platform DMA driver is a kernel device and can have platform data. o DAI and Platform DMA drivers have private data accessors.

Other notable changes required for multi-component support:-

o Decoupled platform DMA and DAI drivers. o Added extern struct siu_info *siu_i2s_data (ideally this should be passed around the sui_dai_ops rather than being a global).

MODULE_LICENSE("GPL"); MODULE_DESCRIPTION("SuperH onchip SSI (I2S) audio driver");

Update the Freescale PPC platform and machines to new multi-component model.

This patch changes the machine drivers for multi-component as follows :-

o Removed socdev o Each DAI link entry now contains platform and codec fields. o DAI link init() now passed snd_soc_pcm_runtime instread of snd_soc_codec.

This patch also changes the DAI and platform DAM drivers as follows :-

o Each platform DAI and platform DMA driver is a kernel device and can have platform data. o DAI and Platform DMA drivers have private data accessors.

Other notable changes required for multi-component support:-

o fsl_ssi_create_dai() and fsl_ssi_destroy_dai() no longer required. o Added mpc5200_hpcd_of_driver of_driver. o Multi-component support for fsl_ssi, fsl_pcm and mpc8610 by Timur Tabi

Update the Analog Blackfin platform and machines to new multi-component model.

This patch changes the machine drivers for multi-component as follows :-

o Removed socdev o Each DAI link entry now contains platform and codec fields. o DAI link init() now passed snd_soc_pcm_runtime instread of snd_soc_codec.

This patch also changes the DAI and platform DAM drivers as follows :-

o Each platform DAI and platform DMA driver is a kernel device and can have platform data. o DAI and Platform DMA drivers have private data accessors.

Other notable changes required for multi-component support:-

o bf5xx_ssm2602_setup data removed as it should be platform data.

Update the Marvell Kirkwood platform and machines to new multi-component model.

This patch changes the machine drivers for multi-component as follows :-

o Removed socdev o Each DAI link entry now contains platform and codec fields. o DAI link init() now passed snd_soc_pcm_runtime instread of snd_soc_codec.

This patch also changes the DAI and platform DAM drivers as follows :-

o Each platform DAI and platform DMA driver is a kernel device and can have platform data. o DAI and Platform DMA drivers have private data accessors.

Other notable changes required for multi-component support:-

o Add platform devices for PCM.
