Hmm I'm not sure if those names are sgx or SoC specific.
Anyways, the sgx clocks for omap variants are already handled
by the ti-sysc module as "fck" and "ick" so nothing to do there.

It would be best to find the clock(s) name used in the sgx docs
to avoid using SoC specific naming :)
But yeah "sysclk" "memclk" and "coreclk" seem just fine for
me for the optional clocks if that works for other SoCs.

Tony
