Is there any plan to move them out of Linux and put them in a separate place?

We should make an effort to sync the device tree files with Linux periodically.

I quite like having the bindings in U-Boot since it makes people think
about what they are adding. Are you worried that the bindings in
U-Boot might evolve separately? Certainly there has been some of that.

However I recently sent a series to add a few things for Raspberry Pi
("arm: rpi: Device tree modifications for U-Boot") and I don't yet see
a willingness to add what some see as 'U-Boot things' to the binding.
How do we address that?

Regards,
Simon
