The device tree is a representation of the hardware itself. The state
of the driver support doesn't change the hardware you're running on,
just like your BIOS/UEFI on x86 won't change the device it reports to
Linux based on whether it has a driver for it.

So yes, unfortunately, we don't have a driver upstream at the
moment. But that doesn't prevent us from describing the hardware
accurately.
