Thanks in advance. The issue is 'dma-masters' is also defined as a uint32 in the Spear binding. Types aren't local to a binding, so when there's a 4 byte value, is that a phandle or plain uint32? I'm working on a fix in dtschema for this. It should be committed shortly. Reviewed-by: Rob Herring (Arm) <robh@xxxxxxxxxx> Rob
