Subject: [PATCH 0/9] Fix support of dw-edma HDMA NATIVE IP in remote setup

From: Kory Maincent <kory.maincent@...tlin.com>

This patch series fix the support of dw-edma HDMA NATIVE IP.
I can only test it in remote HDMA IP setup with single dma transfer, but
with these fixes it works properly.

Few fixes has also been added for eDMA version. Similarly to HDMA I have
tested only eDMA in remote setup.

Kory Maincent (9):
  dmaengine: dw-edma: Fix the ch_count hdma callback
  dmaengine: dw-edma: Typos fixes
  dmaengine: dw-edma: Add HDMA remote interrupt configuration
  dmaengine: dw-edma: HDMA: Add memory barrier before starting the DMA
    transfer in remote setup
  dmaengine: dw-edma: HDMA: Fix possible race condition in remote setup
  dmaengine: dw-edma: HDMA: Fix possible race condition in local setup
  dmaengine: dw-edma: eDMA: Add memory barrier before starting the DMA
    transfer in remote setup
  dmaengine: dw-edma: eDMA: Fix possible race condition in remote setup
  dmaengine: dw-edma: eDMA: Fix possible race condition in local setup
