Should I really drop it? Hmmm, I'm not sure. Is there anything else (besides your driver) that parses this device tree node? dma.txt says this: "The specific strings that can be used are defined in the binding of the DMA client device." So this looks like it's driver-specific, but it is a required property. I guess you should keep it, but I think you should get a second opinion. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
