I would rather not propagate this DT binding. We need to fix the binding
to clearly separate the concepts of:
a) The I2C slave controller (which should be a standalone driver for the
Tegra I2C slave HW).
b) The protocol sent over the I2C slave channel (which would be specific
to NVEC, implement the GPIO hand-shaking, etc.).
c) The devices that communicate over the protocol (keyboard in this case).
I suspect we need separate DT nodes/sub-nodes for all of those, and a
method of hooking them all together.
