No; use an alias in the aliases node.  That is what aliases is designed
for.  Something like 'index' is a reinvention of the wheel.

Do aliases work in reverse?  That is, if I have a pointer to a
device node, can I look up its alias directly?  Or do I have to scan
the aliases node and do a comparison of each phandle, one at a time,
until I find a match?  And when I find a match, will I need to do
sscanf() in order to extract the actual index value from the
property?

Aliases aren't trivially reversible, but it shouldn't be too hard to
write a helper function which will do the scan and parse you describe.
