This series of patches add Freescale ASRC module driver support along with the extra request in imx-sdma structure required by SDMA Device to Device script.
The previous version has been in the maillist for nearly six months without any comment and reply. So I decide to drop the SDMA part's change since this series focus on ASRC support (Later, we can send SDMA part separately.) so that ASRC driver may get upstream first.
Changelog v3: * PATCH-1: Added an Acked-by from Shawn Guo * PATCH-2: Dropped THIS_MODULE as Tobias suggests * PATCH-2: Use dma_coerce_mask_and_coherent() in fsl_asrc_dma_pcm_new() * PATCH-2: Added substream check in fsl_asrc_dma_pcm_new() v2: * PATCH-1: Dropped the change to SDMA driver. * PATCH-2: Dropped useless member in private data structures. * PATCH-2: Refined some comments in fsl_asrc_dma.c driver. * PATCH-2: Refined commit comments.
Nicolin Chen (2): ARM: imx: Add the secondary request into the structure for imx-sdma ASoC: fsl_asrc: Add ASRC ASoC CPU DAI and platform drivers
