Hi,

This series of patches fixes multiple flow control issues with the OMAP
serial driver, and prepares the driver for DMA engine conversion.  We
require hardware assisted flow control to work properly for DMA support
otherwise we have no way to properly pause the transmitter.

All the generic parts
