There is a collection of the current component clock child nodes for each clksel instance. I got warnings with "additionalProperties: false", but maybe the child clock nodes need to be somehow specified in the binding? For example, below is a sample patch for am335x CLKSEL_GFX_FCLK using a clksel parent node with the child nodes moved to fix warnings for unique_unit_address. It also has clock-output-names property added to avoid the node naming warnings. For the other clksel instances, they can be a collection of dividers, multipliers, gates and muxes.
