altos/stm: Set SPI slave DMA priority to HIGH/VERY_HIGH

2016-09-03T06:23:51+00:00

Set spi slave DMA priority MOSI to HIGH and MISO to VERY_HIGH. Slave SPI doesn't have the luxury of slowing down when the system is busy, so provide it maximum memory bandwidth to try and keep up with the master. Signed-off-by: Keith Packard

altos/stm: Set i2c recv DMA to HIGH

2016-09-03T06:23:51+00:00

Make sure receive DMA is higher than any TX dma so that it always runs in preference. Signed-off-by: Keith Packard

altos/stm: Set MISO DMA priority to HIGH to avoid OVR

2016-09-03T06:23:31+00:00

When the MISO DMA priority is too low, and the processor gets busy, it's possible for SPI input to overrun the processor, which causes the MISO DMA to get out of sync and never finish. Set the MISO DMA priority to HIGH to avoid this. Signed-off-by: Keith Packard

altos/stm: Create funcs to set SPI DMA parameters

2016-09-03T05:58:39+00:00

Instead of having nearly duplicate versions of the SPI DMA configuration calls, create helper funcs that do most of the work so that the SPI API funcs are shorter and clearer. Signed-off-by: Keith Packard
