PL-330 DMA driver

[jassi brar]

Hello,

  Many Samsung SoCs have PL-330 as the DMA controller and the driver
is missing in the mainline.

A few months ago, Joonyoung Shim of Samsung, attempted the driver for PL-330
based on the DMA API(drivers/dma/), but the patches weren't accepted.
Perhaps the driver should go into arch/arm/common/ ? Or inconspicuously
into arch/arm/plat-s3cxxxx/ ?

Could maintainers please suggest what is the best place for the PL330
controller driver?

Regards
