Cover letter [PATCH v8 0/4] Determine the number of DMA channels by 'dma-channels' property
The PDMA driver currently assumes there are four channels by default, it might cause the error if there is actually less than four channels. Change that by getting number of channel dynamically from device tree. For backwards-compatible, it uses the default value (i.e. 4) when there is no 'dma-channels' information in dts.
This patch set contains the dts and dt-bindings change.
