| |
Hi Greg,
I would like to create tree like structure using device model (struct device, device_register/device_unregister) using parent/child relationship while creation. I want to be able to create duplicate names, when their parents are different, similar to a directory structure. I see that I can't create devices with duplicate names (device names), even when their parents are different.
How can I allow duplicate names when their parents are different devices? I want to avoid flat model as I have parent child relationship and there will be too many devices using flat model.
Why, I need? I am going to publish RFC for a new power cap class driver. We have a multiple controllers under power cap class (they are devices). Under which there are multiple power zones, with parent/child relationships. Currently I have to use kobject_init_and_add, which I want to avoid and just use device_register. Other places, wherever such relationships are required, kobjects are used like cpufreq.
Thanks, Srinivas Pandruvada Open Source Technology Center, Intel Corp.
