Add the flag to the relevant clocks in the C code, e.g. in clk_register_flexgen(): if (!strcmp(name, "clk-icn-cpu")) init.flags |= CLK_ENABLE_HAND_OFF; > Could we imagine having a kind of "clocks-enable-hand-off" property we could > use in our clock controller DT node? You can imagine doing "flex_flags |= CLK_ENABLE_HAND_OFF" in st_of_flexgen_setup(), depending on the presence of such a property. However, not disabling clocks is a software policy, not a hardware description, so IMHO it doesn't belong in DT.
