Subject: [PATCH 0/6] Allwinner H6 DMA support

DMA engine on H6 is almost the same as on older SoCs. The biggest
difference is that it has slightly rearranged bits in registers and
it needs additional clock, probably due to iommu.

These patches were tested with I2S connected to HDMI. I2S needs
additional patches which will be sent later.

Please take a look.

Best regards,
Jernej
