Shengjiu Wang	b287a6d972	ASoC: fsl_asrc_dma: Fix data copying speed issue with EDMA ... With EDMA, there is two dma channels can be used for dev_to_dev, one is from ASRC, one is from another peripheral (ESAI or SAI). If we select the dma channel of ASRC, there is an issue for ideal ratio case, the speed of copy data is faster than sample frequency, because ASRC output data is very fast in ideal ratio mode. So it is reasonable to use the dma channel of Back-End peripheral. then copying speed of DMA is controlled by data consumption speed in the peripheral FIFO, Signed-off-by: Shengjiu Wang <shengjiu.wang@nxp.com> Reviewed-by: Nicolin Chen <nicoleotsuka@gmail.com> Link: https://lore.kernel.org/r/424ed6c249bafcbe30791c9de0352821c5ea67e2.1591947428.git.shengjiu.wang@nxp.com Signed-off-by: Mark Brown <broonie@kernel.org>	2020-06-12 14:18:04 +01:00
Shengjiu Wang	be7bd03f02	ASoC: fsl_asrc: Move common definition to fsl_asrc_common ... There is a new ASRC included in i.MX serial platform, there are some common definition can be shared with each other. So move the common definition to a separate header file. And add fsl_asrc_pair_priv and fsl_asrc_priv for the variable specific for the module, which can be used internally.
