Hopefully this will be the last time we need to pester you about this.
What should we be using instead of cell-index to identify multiple
instances of a device?
To give you an idea of what the code looks like right now:
ret = of_property_read_u32(dev->of_node, "cell-index", &index);
if (ret)
index = 0;
[...]
dev_set_name(dpfe_dev, "dpfe%u", index);
ret = device_register(dpfe_dev);
Enumerating the devices like this is what we are after.
Thanks,
-Markus
