Will change this. Also why not call it without explicit soc check? there is already parse for of_find_matching_node(NULL, crossbar_match); to see if we have a match in the crossbar_init. OR call it from dra7 init without SoC check dependency? Rationale - with more TI SoCs trending towards crossbar, we dont need to keep adding to the soc_is checks, further, we intend to remove soc_is checks in it's entirety..

So hope is that we don't have to use this infrastructure always but only for exceptional cases. Regards, Santosh
