[RESEND][PATCH 0/3] dma: pl330: Simplify platform data for pl330 driver

[Thomas Abraham]

The rqtype parameter specified in platform data as part of the
'struct dma_pl330_peri' can be infered from the direction of the transfer
specified with transfer requests. So the rqtype parameter can be removed
and 'struct dma_pl330_peri' is then left with only one field 'peri_id'
which itself can be moved into 'struct dma_pl330_platdata' and the
entire 'struct dma_pl330_peri' can be eliminated.

This is first step towards adding device tree support for pl330 dma driver.
With rqtype information inferred from transfer requests, it need not be
included in device tree to describe each hardware dma request.

This patchset is based on following tree.
http://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung.git
and branch 'kgene/next/topic-dma-pl330'.

This patchset has been implemented and tested only for Exynos4. If this
patchset is acceptable, then pl330 driver platform data for other samsung
platforms will also be modfied.
