Subject: [PATCH v2 0/3] dmaengine: bindings/edma: dma-channel-mask to array

Hi,

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.

Rob: I'm not sure if I got the dma-common.yaml update correctly...

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
