You can drop the model property here since this doesn't define a board.

Which arm intc controller? For any new 'compatible' value you define,
the patch needs to include documentation for it in
Documentation/devicetree/bindings.

Probably should be "ti,omap3-l4-core"?

Drop the 'status' properties. I know the current tegra code does
this, but I'd prefer devices to be enabled by default and for boards
to explicitly disable them instead of the other way around.
