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.
