Hi,
After DMA burst mode has been introduced in sound/soc/omap/omap-pcm.c,
omap_pcm_prepare() unconditionally calls:
omap_set_dma_src_burst_mode(prtd->dma_ch, OMAP_DMA_DATA_BURST_16);
omap_set_dma_dest_burst_mode(prtd->dma_ch, OMAP_DMA_DATA_BURST_16);
AFAICS, current implementation of those two functions found in
arch/arm/plat-ompa/dma.c doesn't support OMAP_DMA_DATA_BURST_16 on OMAP1 at
all, so they both end with BUG() on that machine. That seems to result in
ASoC being completely unusable, at least on my OMAP5910 based Amstrad Delta.
Is calling BUG() for OMAP1 from those functions intentional?
If not intentional, can those be corrected by simply putting break; before
defalut:?
If intentional, can those function calls be conditionally omited, at least for
OMAP1510, in sound/soc/omap/omap-pcm.c?
Thanks,
Janusz
