The binding may be trivial, but there's a bigger question of whether
this is the right long term direction. For example is upstream QEMU
going to take all the Android pipe stuff? Couldn't virtio be used here
as the transport?

But I wonder if that should really block this from being merged?  The
support may not be in QEMU but it's in the Android emulator and it would
be a less broken implementation with these patches in the kernel than
without, I think.

To add to Christoffer's point, we added these bindings so we don't need to
rely on the goldfish virtual bus for probing anymore.

Switching from the goldfish virtual bus to Device-Tree already eliminates
one big piece where the Android emulator has diverged from upstream qemu.
And on the kernel side, it means we don't need ARM and MIPS goldfish board
code to instantiate the bus.

Okay, fair enough. That's not evident from the patch.
