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.

The driver library functions can be used directly by the compound devices such
as ADSP or serial driver where DesignWare DMA IP is privately attached to the
main hardware.
Instead of creating a new platform device leaf they may call dw_dma_probe()
with given struct dw_dma_chip directly and make sure that the main device is
DMA capable.

The introduced include/linux/dma/dw.h is going to contain the private
extensions and structures which are shared for dw_dmac users in the kernel.
Meanwhile include/linux/platform_data/dma-dw.h keeps only platform related data
types and definitions.

PXA peripherals need to obtain specific DMA request ids which will
eventually be stored in the DRCMR register.
Currently, clients are expected to store that number inside the slave
config block as slave_id, which is unfortunately incompatible with the
way DMA resources are handled in DT environments.
This patch adds a filter function which stores the filter parameter
passed in by of-dma.c into the channel's drcmr register.
For backward compatability, cfg->slave_id is still used if set to
a non-zero value.

The header ipu.h really belongs to dma subsystem rather than imx
platform. Rename it to ipu-dma.h and put it into include/linux/dma/.
