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. > The hyd_clk at sunxi devices seems to be the system clock. > > With those additional information it should be very easy to get a proper > binding. 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.
