* OMAP3: McBSP: Lower the maximum buffersize for McBSP1, 3, 4, 5Peter Ujfalusi2009-08-201-4/+4
| | | | | | | | | | | Do not allow applications to use the full buffer found on McBSP1,3,4,5. Using the full buffer in threshold mode causes the McBSP buffer to run dry, which can be observed as channels are switching (in reality the channels are shifting).

* ASoC: OMAP: Make use of DMA channel self linking on OMAP1510Janusz Krzysztofik2009-08-171-7/+8
| | | | | | | | | | | | | | | | | | | | | | | | Use newly implemented DMA channel self linking on OMAP1510 like on other OMAP models. Remove unnecessary DMA transfer restart from interrupt handler routine. The interrupt routine used to maintain a period index, originally needed for counting up periods up to a full buffer in order to restart the DMA transfer. For some time, this counter is also used as a replacement for hardware DMA progress counter that has been found unusable on OMAP1510 in case of playback. Thus, the period index calculation cannot be omitted completely. However, the accuracy of this counter can still suffer from missing DMA interrupts. In order to work correctly, it requires patch 1 from this series also applied: [RFC][PATCH 1/3] ARM: OMAP: DMA: Add support for DMA channel self linking on OMAP1510 Created against linux-2.6.31-rc5.

This FIFO provides additional data buffering. It also provides tolerance to variation in host/DMA controller response times. The read and write FIFO sizes are 256 bytes each. If FIFO is enabled, the DMA events from McASP are sent to the FIFO which in turn sends DMA requests to the host CPU according to the thresholds programmed. More details of the FIFO operation can be found at http://focus.ti.com/general/docs/lit/getliterature.tsp?literatureNumber= sprufm1&fileType=pdf This patch adds support for FIFO configuration. The platform data has a version field which differentiates the McASP on different SoCs.
