DMA clients pdma0 and pdma1 are internal to the SoC and are used only
by dedicated peripherals. Since they cannot be used for generic
purpose, their capability should be set as DMA_PRIVATE.

The patches are rebased on top of v3.6-rc3.

Hi Vinod,

Looks good to me, please pick them into your tree with my ack.

Acked-by: Kukjin Kim <kgene.kim@samsung.com>

If any problems, please kindly let me know.

Thanks.

Best regards,
Kgene.
