Exactly!  The device tree is supposed to describe the hardware from a
functional perspective, so the fact that something is implemented in
an fpga or cpld is irrelevant, what matters is what's inside the fpga.

If an fpga was used to implement an ethernet MAC, we'd call if
"ethernet", if something else, something else.  If it was designed to
be programmed at runtime by the OS, then we'd probably call it "fpga",
but otherwise it should be named for what's inside it.
