Here are clean up and big refactoring against Synopsys DesignWare DMA driver.

Some fixes are related to Intel iDMA 32-bit type of controller
which has been tested on Intel Merrifield platform.

The big refactoring splits out specific DW and iDMA 32-bit parts
for better maintenance.

Changelog v3:
- rebase on top of v5.0-rc1
- drop Fixes tag from patch 1, it's simple an enhancement (Vinod)
- use proper format for SPDX for header files (Vinod)
- add Greg KH's ACK

Changelog v2:
- rebase on top of topic/dw branch of dmaengine subsystem
- append few more patches, especially one that removes is_private property
- fix code kbuild bot complains about
- fix some typos which slipped during refactoring and haven't been noticed
  during test

Andy Shevchenko (7):
  dmaengine: dw: Add missed multi-block support for iDMA 32-bit
  dmaengine: dw: Remove misleading is_private property
  dmaengine: dw: Remove unused internal property
  dmaengine: dw: Split DW and iDMA 32-bit operations
  dmaengine: dw: Reset DRAIN bit when resume the channel
  dmaengine: dw: Don't pollute CTL_LO on iDMA 32-bit
  dmaengine: dw: convert to SPDX identifiers
