[PATCH V3 0/3] Add DMA support for transfers in multiple cases

[pandith.n@intel.com]

From: Pandith N <pandith.n@intel.com>

This series adds dma support in following transfers
mem2mem: set dma coherent mask
mem2per: memory to peripheral with hardware handshake control, when APB
register extension is not provided.
per2mem: peripheral to memory with hardware handshake control, when APB
register extnesion is not provided

Support DMAX_NUM_CHANNELS > 8
--------------------------------------------
Depending on number of channels the register map changes in DMAC.
DMA driver now supports both register maps based of number of
channels used in platform.

Setting hardware handshake for peripheral transfers
-----------------------------------------------------------------------
mem2per and per2mem transfers are supported with hardware handshake
control, without apb register extension.

setting dma coherent mask
--------------------------------------------------
Added 64-bit dma coherent mask setting

Pandith N (3):
  dmaengine: dw-axi-dmac: support DMAX_NUM_CHANNELS > 8
  dmaengine: dw-axi-dmac: Hardware handshake configuration
  dmaengine: dw-axi-dmac: set coherent mask
