  dmaengine: edma: Add dummy driver skeleton for edma3-tptc (2015-11-04 22:11:42 +0530)

----------------------------------------------------------------
dmaengine updates for 4.4-rc1

This time we have a very typical update which is mostly fixes and updates to
drivers and no new drivers.

- Biggest change is coming from Peter for edma cleanup which even caused
  some last minute regression, things seem settled now
- idma64 and dw updates
- iotdma updates
- module autoload fixes for various drivers
- scatter gather support for hdmac
