Hi, The core DT schema defines generic 'dma-channels' and 'dma-requests' properties, so in preparation to moving bindings to DT schema, convert existing users of '#dma-channels' and '#dma-requests' to the generic variant. Not tested on hardware. The patchset is bisectable - please pick up through independent trees. Changes since v1 ================ 1. Keep old properties, so the patchset is bisectable. 2. Add review tags.
