Does not look like you tested the DTS against bindings. Please run `make
dtbs_check` (see Documentation/devicetree/bindings/writing-schema.rst
for instructions).

Use consistent naming. If other is "-clk" this should be as well.

Isn't this located on the board? Physically on the board?

These are not allowed on their own. Your patchset is really not tested
against bindings.

NAK even more, you do not have children.

So your entire SoC is just bunch of syscons and interrupt controller.
That's not suitable for upstream at all. Define a real hardware and a
real DTS.
