Hi,
Here come patches overhauling the Samsung ASoC support.
The AC97, PCM, SPDIF and ASoC-DMA related code has merely undergone cosmetic changes - symbol, device & driver renaming and file moving.
A new I2S controller driver has been added to manage Samsung SoCs since S3C64XX. Older driver has been changed only as is necessary. Regarding I2S, I have left the s3c24xx series untouched because the controllers are too different to run by a common driver. S3C2412's I2S does have some similarities, but not important enough to warrant impact on new driver design. The new I2S driver has been designed around the notion of features/quirks. The newer SoCs have revised version of I2S_0(usually) than previous ones. So, I2S block is 'specified' in the platform code and the driver works on that configuration. For now, Secondary I2S DAI works only with System-DMAC. I2S-Internal DMA and SRAM will be enabled later.
Testing:- Simple testing of 5.1 channel and hardware mixing seems to work (though there seems to be some issue with symmetric_rates in soc-core.c which would be tried to fix later as saperate issue). I would appreciate any test-results for GONI and SMARTQ.
I suggest the patches 13,14,16 & 17 go via Kgene's Tree, and the rest via ASoC tree due to tight dependencies.
