This patchset adds slave DMA support for Actions Semi S900 SoC of the
Owl family. As a consumer, enable TX DMA support for UART peripheral
in S900. The UART driver still supports interrupt mode if there is no
DMA property specified in DT.

The dts patch depends on the previous DMA patches which is not yet
merged.

Thanks,
Mani
