Browse source 
- dmatest updates for modularizing common struct and code
  - remove SG support for VDMA xilinx IP and updates to driver
  - Update to dw driver to support Intel iDMA controllers
    multi-block support
  - tegra updates for proper reporting of residue
  - Add Snow Ridge ioatdma device id and support for IOATDMA v3.4
  - struct_size() usage and useless LIST_HEAD cleanups in subsystem.
  - qDMA controller driver for Layerscape SoCs
