Subject: [PATCH v5 0/3] dmaengine: bindings/edma: dma-channel-mask to array

Hi,

Changes since v4:
- Rebased on next to make it apply cleanly
- Added Reviewed-by from Rob for the DT documentation patches

Changes since v3:
- Update the dma-common.yaml and edma binding documentation according to Rob's
  suggestion

Changes since v2:
- Fix dma-common.yaml documentation patch and extend the description of the
  dma-channel-mask array
- The edma documentation now includes information on the dma-channel-mask array
  size for EDMAs with 32 or 64 channels

Changes since v1:
- Extend the common dma-channel-mask to uint32-array to be usable for
  controllers with more than 32 channels
- Use the dma-channel-mask instead custom property for available channels for
  EDMA.

The original patch was part of the EDMA multicore usage series.

EDMAs can have 32 or 64 channels depending on the SoC, the dma-channel-mask
needs to be an array to be usable for the driver.

Regards,
Peter
