Fix for address auto-incrementation flags for DMA transmissions for
PXA2xx sound.
Old version used playback settings for recording, so it wrongly read
from whole register space (instead of one FIFO register) and wrote into
single word in memory.

Your patch has all tabs replaced by spaces, so can't be applied.

Add support for SCCB devices into PXA27x I2C controller.
Fix generated START but no STOP for message without I2C_M_NOSTART flag. Add support for I2C_M_IGNORE_NAK flag.
