device_type is deprecated and the kernel doesn't require it in most
cases. The only exceptions for flat tree users are the "gianfar",
"ucc_geth" and "ibm,emac" bindings, and arguably that requirement could
be relaxed for ucc_geth and ibm,emac (that is a task for separate
patches though).

This patch removes references to device_type="network" from the binding
documentation where possible and removes the properties from ARM and
microblaze dts files. This patch does not modify the powerpc .dts files
since there are a much larger number of them affected and I think the
ucc_geth, ibm,emac and gianfar users should be addressed before clearing
out the references to reduce the chance of breakage.

btw: what device types can be used?
I am having them for serial, watchdog, pci, memory, cpu, ethernet-phy
(will remove network from our generator).

when I grep kernel there are others types like soc, ipmi and a lot for powerpc.

There are a number of users, but most of them are bogus since they can
just as easily be expressed via a compatible value. There are a few
cases where they are required. PCI bus nodes, memory nodes, and cpus for
example. General rule here is avoid device_type entirely unless some
core infrastructure of the kernel requires it.
