Forum Post: How to add support for new am335x core frequency using Sitara SDK 7.0

Hey all,

I know it is possible to set the core clk frequency below the OPP50 spec, but I can not figure out how to do it.

Does anybody know where inside the omap/am335x linux "driver" source code (using SDK 7.0) these registers and values are being hard coded as OPP options? Or how to go about solving this in general?

I realize that it might be more complicated than changing the values of one or two #defines, but any help is appreciated.

Thanks,

Nolan
