Subject: [PATCH v2 0/1] ARM: dmaengine: sun6i: share the dma driver with sun50i

Hi,

This patch add the allwinner soc a64 dma support on already done driver
sun6i-dma.

A64 is a 64bit SOC, it has 8 channel DMA which flexible
data width of 8/16/32/64-bit. Detailed info about it is on
Allwinner_A64_User_Manual_V1.0 page 196 and A64_Datasheet_V1.1 page 8.

Due to the patch of clocks, device tree and other support for a64 is not merged,
this patch does not contain the support about them.

It has been test on pin64 using dmatest.

Regards,
Hao Zhang
