That's a quite generic compatible. axi is ARM term, 1-wire is the name
of the bus and master is the role. Concatenating three common words does
not create unique device name. Compatibles are supposed to be specific
and this is really relaxed. Anything can be over AXI, everything in
1wire is 1wire and every master device is a master.
