Heikki Krogerus	4c97ad993d	dmaengine: hsu: remove platform data ... There are no platforms where it's not possible to calculate the number of channels based on IO space length, and since that is the only purpose for struct hsu_dma_platform_data, removing it.

Heikki Krogerus	47f82f1adf	dmaengine: hsu: introduce stubs for the exported functions ... This allows UART drivers to register HSU DMA Engine without being forced to use ifdefs.

Andy Shevchenko	2b49e0c567	dmaengine: append hsu DMA driver ... 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.
