I will fix it ! OK, so given there are several cooks in the kitchen, and I just read these replies after replying independently to the binding doc, I'll try to summarize the consensus, flavored with my own opinion: * the node name should not be 'nor'; it should be something more along the lines of ePAPR. So 'flash' or 'spi' * the phandle name is less important, and can be more descriptive * there should be a subnode to represent the flash separately from the controller So we might put this together to: whatever_name_you_like: spi@1100d000 { ... flash@0 { ... }; }; Brian -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
