What if instead we added something like OF_ALIASES to the uevent
attribute? Then userspace would have access to all the aliases for a
device. Heck, even a shell script can parse the uevent attribute. There
is also precedence for exporting OF data using a uevent. This is from
the versatile device tree support:
# cat /sys/devices/amba.0/uevent
OF_NAME=amba
OF_FULLNAME=/amba
OF_COMPATIBLE_0=arm,amba-bus
OF_COMPATIBLE_N=1
MODALIAS=of:NambaT<NULL>Carm,amba-bus
This sounds like a good idea. I have just sent out a new patch to do
this. I followed the OF_COMPATIBLE uevent convention for listing the
aliases, but I can follow another convention if someone objects.
