This series add DMA support for UARTs on AM654 and J721e SoCs. These
UARTs are modified version of older generation UARTs on OMAP SoCs.

With new version of IP, it is possible to support longer DMA bursts per
request. There are also differences wrt DMA integration.

First 4 patches update driver to work with AM654 DMA differences. Patch
5 implements errata workaround and Patch 6 adds the actual support for
DMA.
