The HSU DMA is developed to support High Speed UART controllers found in particular on Intel MID platforms such as Intel Medfield. The existing implementation is tighten to the drivers/tty/serial/mfd.c driver and has a lot of disadvantages. Besides that we would like to get rid of the old HS UART driver in regarding to extending the 8250 which supports generic DMAEngine API. That's why the current driver has been developed.

Support the High Speed UART DMA on the platfroms that
|
|
enumerate it as a PCI device. For example, Intel Medfield
|
|
has integrated this HSU DMA controller.
