protocol to list input (physical) devices

[Vasyl Vavrychuk]

I have written a small application for sending input events for test
purposes using uinput.

But, after I create uinput event device, I don't know how to wait
until wayland picks it up.

Could there be a way to list physical input devices available via
wayland protocol? Similarly how wl_output is used to list outputs.

Kind regards,
Vasyl
