If an OSS application calls SNDCTL_DSP_SYNC, then ALSA will call the driver's _hw_params and _prepare functions again. On the Freescale MPC8610 DMA ASoC driver, this caused the DMA controller to be unneccessarily re-programmed, and apparently it doesn't like that. The DMA will then not operate when instructed. This patch relocates much of the DMA programming to fsl_dma_open(), which is called only once. Signed-off-by: NTimur Tabi <timur@freescale.com> Signed-off-by: NTakashi Iwai <tiwai@suse.de>

The Freescale MPC8610 SSI device has the option of using one clock for both transmit and receive (synchronous mode), or independent clocks (asynchronous). The SSI driver, however, programs the SSI into synchronous mode and then tries to program the clock registers independently. The result is that the wrong sample size is usually generated during recording. This patch fixes the discrepancy by restricting the sample rate and sample size of the playback and capture streams. The SSI driver remembers which stream is opened first. When a second stream is opened, that stream is constrained to the same sample rate and size as the first stream. A future version of this driver will lift the sample size restriction. Supporting independent sample rates is more difficult, because only certain codecs provide dual independent clocks.

Enable mmap support in the MPC8610 ASoC driver. The driver can use ALSA's default mmap functionality, it was just not enabled previously. Signed-off-by: NTimur Tabi <timur@freescale.com> Signed-off-by: NTakashi Iwai <tiwai@suse.de> Signed-off-by: NJaroslav Kysela <perex@perex.cz>
