I thought cell-index was "deprecated" and referred more to things like enumerating all the devices on a bus by assigning them a unique ID. Aliases, on the other hand, allow us to enumerate a subset of devices that share the same bus with other devices of different types. For example, how would I know that a device is gsbi1 vs serial1 if they both used cell-index and they both had the same parent node? -- Qualcomm Innovation Center, Inc. is a member of Code Aurora Forum, a Linux Foundation Collaborative Project -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
